     /**
     * @name kendo.ui.Globalization.Description
     *
     * @section Globalization is the process of designing and developing an
     * application that works in multiple cultures. The culture defines specific information
     * for the number formats, week and month names, date and time formats and etc.
     *
     * @section Kendo exposes <strong><em>culture(cultureName)</em></strong> method which allows to select the culture
     * script coresponding to the "culture name". kendo.culture() method uses the passed culture name
     * to select culture from the culture scripts that you have included and then sets the current culture.
     * If there is no such culture, the default one is used.
     *
     * <h3>Define current culture settings</h3>
     *
     * @exampleTitle Include culture scripts and select culture
     * @example
     *
     * <script src="jquery.js" ></script>
     * <script src="kendo.all.min.js"></script>
     * <script src="kendo.culture.en-GB.js"></script>
     * <script type="text/javascript">
     *    //set current culture to the "en-GB" culture script.
     *    kendo.culture("en-GB");
     * </script>
     *
     * @exampleTitle Get current culture
     * @example
     * var cultureInfo = kendo.culture();
     *
     * @section
     * <h3>Format number or date object</h3>
     *
     * Kendo exposes methods which can format number or date object using specific format string and the current specified culture:
     * @section
     * <h4><code>kendo.toString(object, format)</code> - returns a string representation of the current object using specific format.</h4>
     * @exampleTitle Formats number and date objects
     * @example
     * //format number using standard number format
     * kendo.toString(10.12, "n"); //10.12
     * kendo.toString(10.12, "n0"); //10
     * kendo.toString(10.12, "n5"); //10.12000
     * kendo.toString(10.12, "c"); //$10.12
     * kendo.toString(0.12, "p"); //12.00 %
     * //format number using custom number format
     * kendo.toString(19.12, "00##"); //0019
     * //format date
     * kendo.toString(new Date(2010, 9, 5), "yyyy/MM/dd" ); // "2010/10/05"
     * kendo.toString(new Date(2010, 9, 5), "dddd MMMM d, yyyy" ); // "Tuesday October 5, 2010"
     * kendo.toString(new Date(2010, 10, 10, 22, 12), "hh:mm tt" ); // "10:12 PM"
     *
     * @section
     * <h4><code>kendo.format</code> - replaces each format item in a specified string with the text equivalent of a corresponding object's value.</h4>
     *  @exampleTitle String format
     *  @example
     *  kendo.format("{0} - {1}", 12, 24); //12 - 24
     *  kendo.format("{0:c} - {1:c}", 12, 24); //$12.00 - $24.00
     *
     * @section
     * <h3>Parsing a string</h3>
     *
     * Kendo exposes methods which converts the specified string to date or number object:
     * <ol>
     *    <li>
     *       <code>kendo.parseInt(string, [culture])</code> - converts a string to a whole number using the specified culture (current culture by default).
     *        @exampleTitle Parse string to integer
     *        @example
     *
     *        //assumes that current culture defines decimal separator as "."
     *        kendo.parseInt("12.22"); //12
     *
     *        //assumes that current culture defines decimal separator as ",", group separator as "." and currency symbol as "€"
     *        kendo.parseInt("1.212,22 €"); //1212
     *    </li>
     *    <li>
     *       <code>kendo.parseFloat(string, [culture])</code> - converts a string to a number with floating point using the specified culture (current culture by default).
     *        @exampleTitle Parse string to float
     *        @example
     *
     *        //assumes that current culture defines decimal separator as "."
     *        kendo.parseFloat("12.22"); //12.22
     *
     *        //assumes that current culture defines decimal separator as ",", group separator as "." and currency symbol as "€"
     *        kendo.parseFloat("1.212,22 €"); //1212.22
     *    </li>
     *    <li>
     *       <code>kendo.parseDate(string, [formats], [culture])</code> - converts a string to a JavaScript Date object, taking into account the given format/formats (or the given culture's set of default formats).
     *       Current culture is used if one is not specified.
     *        @exampleTitle Parse string to float
     *        @example
     *
     *        //current culture is "en-US"
     *        kendo.parseDate("12/22/2000"); //Fri Dec 22 2000
     *        kendo.parseDate("2000/12/22", "yyyy/MM/dd"); //Fri Dec 22 2000
     *    </li>

     *  @name kendo.ui.Validator.Description
     *
     *  @section
     *  <p>
     *     Validator offers an easy way to do client-side form validation.
     *     Built around the HTML5 form validation attributes it supports variety of built-in validation rules, but also provides a convenient way for setting custom rules handling.
     *  </p>
     *  @exampleTitle <b>Validator</b> initialization to validate input elements inside a container
     *  @example
     *  <div id="myform">
     *   <input type="text" name="firstName" required />
     *   <input type="text" name="lastName" required />
     *   <button id="save" type="button">Save</button>
     *  </div>
     *
     *  <script>
     *   $(document).ready(function(){
     *       var validatable = $("#myform").kendoValidator().data("kendoValidator");
     *       $("#save").click(function() {
     *          if (validatable.validate()) {
     *              save();
     *          }
     *       });
     *   });
     *   </script>
     *  @section <h4>Validation Rules</h4>
     *
     *  @exampleTitle <strong>required</strong>- element should have a value
     *  @example
     *  <input type="text" name="firstName" required />
     *
     *  @exampleTitle <strong>pattern</strong>- constrains the value to match a specific regular expression
     *  @example
     *  <input type="text" name="twitter" pattern="https?://(?:www\.)?twitter\.com/.+i" />
     *
     *  @exampleTitle <strong>max/min</strong>- constrain the minimum and/or maximum numeric values that can be entered
     *  @example
     *  <input type="number" name="age" min="1" max="42" />
     *
     *  @exampleTitle <strong>step</strong>- when used in combination with the min and max attributes, constrains the granularity of values that can be entered
     *  @example
     *  <input type="number" name="age" min="1" max="100" step="2" />
     *
     *  @exampleTitle <strong>url</strong>- constrain the value to being a valid URL
     *  @example
     *  <input type="url" name="url" />
     *
     *  @exampleTitle <strong>email</strong>- constrain the value to being a valid email
     *  @example
     *  <input type="email" name="email" />
     *
     *  @section
     *  <p>Beside the built-in validation rules, KendoUI Validator also provides a convenient way for setting custom rules through its rules configuration option. </p>
     *
     *  @exampleTitle
     *  @example
     *  $("#myform").kendoValidator({
     *      rules: {
     *        custom: function(input) {
     *          // Only Tom will be a valid value for FirstName input
     *          return input.is("[name=firstname]") && input.val() === "Tom";
     *        }
     *      }
     * });
     *
     *  @section <h4>Validation Messages</h4>
     *  <p>There are several ways to control the messages which appears if validation fails:</p>
     *
     *  @exampleTitle Set the validation messages for all input elements, through configuration options
     *  @example
     *   $("#myform").kendoValidator({
     *      rules: {
     *          custom: function(input) {
     *                  //...
     *          }
     *      },
     *      messages: {
     *        // defines message for the 'custom' validation rule
     *        custom: "Please enter valid value for my custom rule",
     *        // overrides the built-in message for required rule
     *        required: "My custom required message",
     *        // overrides the built-in email rule message with a custom function which return the actual message
     *        email: function(input) {
     *          return getMessage(input);
     *        }
     *     }
     *  });
     *  @exampleTitle Use the title and validationMessage attributes to set per input element messages
     *  @example
     *     <input type="tel" pattern="\d{10}" validationMessage="Plase enter a ten digit phone number" />
     *
     *  @section <h4>Triggering validation</h4>
     *  <p>In order to trigger the element(s) validation, <strong>validate</strong> method should be used. It will return either <em>true</em> if validation succeeded or <em>false</em> in case of a failure. </p>
     *  <p>
     *  Note that if a HTML form element is set as validation container, the form submits will be automatically prevented if validation fails.
     *  </p>
     *  @section <h4>Initialize Kendo Validator with specific tooltip position</h4>
     *
     *  <p>
     *      Ideally Kendo Validator places its tooltips besides the validated input. However, if the input is later enhanced to a ComboBox, AutoComplete or other Kendo Widget, placing the
     *      tooltip beside the input may cover important information or break the widget rendering. In this case, you can specify where exactly do you want the tooltip to be placed by
     *      adding a span with data-for attribute set to the validated input ID and a class .k-invalid-msg. Check the example below:
     *  </p>
     *
     *  @exampleTitle <b>Validator</b> initialization with specific tooltip placement (the tooltip will remain outside of the AutoComplete widget after enhancement)
     *  @example
     *  <div id="myform">
     *      <input type="text" id="name" name="name" required />
     *      <span class="k-invalid-msg" data-for="name"></span>
     *  </div>
     *
     *  <script>
     *      $("#name").kendoAutoComplete({
     *                     dataSource: data,
     *                     separator: ", "
     *                 });
     *
     *      $("#myform").kendoValidator();
     *  </script>

     * @section
     * <p>
     *  The <b>Calendar</b> renders a graphical calendar that supports
     *  navigation and selection. It supports custom templates for its
     *  "month" view, configurable options for a minimum and maximum date,
     *  start view and the depth of the navigation.
     * </p>
     * <h3>Getting Started</h3>
     *
     * @exampleTitle Create a div element
     * @example
     * <div id="calendar"></div>
     *
     * @exampleTitle Initialize the Calendar via a jQuery ID selector
     * @example
     * $(document).ready(function(){
     *  $("#calendar").kendoCalendar();
     * });
     *
     * @section
     * <p>
     *  When a <b>Calendar</b> is initialized, it will automatically be
     *  displayed near the location of the used HTML element.
     * </p>
     * <h3>Configuring Calendar Behaviors</h3>
     * <p>
     *  The <b>Calendar</b> provides many configuration options that can be
     *  easily set during initialization. Among the properties that can be
     *  controlled:
     * </p>
     * <ul>
     *  <li>Selected date</li>
     *  <li>Minimum and/or maximum date</li>
     *  <li>Start view</li>
     *  <li>
     *   Define the navigation depth (last view to which end user can
     *   navigate)
     *  </li>
     *  <li>Day template</li>
     *  <li>Footer template</li>
     * </ul>
     *
     * @exampleTitle Create Calendar with selected date and a defined minimum
     * and maximum date
     * @example
     * $("#calendar").kendoCalendar({
     *  value: new Date(),
     *  min: new Date(1950, 0, 1),
     *  max: new Date(2049, 11, 31)
     * });
     *
     * @section
     * <p>
     *  The <b>Calendar</b> will not navigate before than the minimum
     *  date specified. It will also not navigate ahead the maximum date
     *  specified.
     * </p>
     * @section
     * <h3>Define start view and navigation depth</h3>
     * <p>
     *  The first rendered view can be defined with "start" option.
     *  Navigation depth can be controlled with "depth" option. Predefined
     *  views are:
     *  <ul>
     *   <li>"month" - shows the days from the month</li>
     *   <li>"year" - shows the months of the year</li>
     *   <li>"decade" - shows the years from the decade</li>
     *   <li>"century" - shows the decades from the century</li>
     *  </ul>
     * </p>
     *
     * @exampleTitle Create a Calendar, which allows a user to select a month
     * @example
     * $("#calendar").kendoCalendar({
     *  start: "year",
     *  depth: "year"
     * });
     *
     * @section
     * <h3>Customize day template</h3>
     * <p>
     *  The <b>Calendar</b> allows to customize content of the rendered day
     *  in the "month" view.
     * </p>
     *
     * @exampleTitle Create a Calendar with custom template
     * @example
     * $("#calendar").kendoCalendar({
     *  month: {
     *   content: '<div class="custom"><#=data.value#></div>'
     *  }
     * });
     *
     * @section
     * <p>
     *  This templates wraps the "value" in a div HTML element. Here is an
     *  example of the object passed to the template function:
     * </p>
     *
     * @exampleTitle Structure of the data object passed to the template
     * @example
     * data = {
     *  date: date, // Date object corresponding to the current cell
     *  title: kendo.toString(date, "D"),
     *  value: date.getDate(),
     *  dateString: "2011/0/1" // formatted date using yyyy/MM/dd format and month is zero-based
     * };
     *
     * @section
     * <h3>Accessing an Existing Calendar</h3>
     * <p>
     *  You can reference an existing <b>Calendar</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>.
     *  Once a reference has been established, you can use the API to control
     *  its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing Calendar instance
     * @example
     * var calendar = $("#calendar").data("kendoCalendar");

     * @name kendo.ui.DatePicker.Description
     *
     * @section
     * <p>
     *  The <b>DatePicker</b> allows the end user to select a date from a
     *  calendar or by direct input. It supports custom templates for "month"
     *  view, configurable options for min and max date, start view and the
     *  depth of the navigation.
     * </p>
     * <h3>Getting Started</h3>
     *
     * @exampleTitle Creating a DatePicker from existing input element
     * @example
     * <input id="datePicker" />
     *
     * @exampleTitle DatePicker initialization
     * @example
     * $(document).ready(function(){
     *  $("#datePicker").kendoDatePicker();
     * });
     *
     * @section
     * <p>
     *  When a <b>DatePicker</b> is initialized, it will be displayed at the
     *  location of the target HTML element.
     * </p>
     * <h3>Configuring DatePicker Behaviors</h3>
     * <p>
     *  The <b>DatePicker</b> provides configuration options that can be set
     *  during initialization. Among the properties that can be controlled:
     * </p>
     * <ul>
     *  <li>Selected date</li>
     *  <li>Minimum and/or maximum date</li>
     *  <li>Define format</li>
     *  <li>Start view</li>
     *  <li>Navigation depth (last view to which end user can navigate)</li>
     * </ul>
     *
     * @exampleTitle Create DatePicker with a selected date and a defined
     * minimum and maximum date
     * @example
     * $(document).ready(function(){
     *  $("#datePicker").kendoDatePicker({
     *   value: new Date(),
     *   min: new Date(1950, 0, 1),
     *   max: new Date(2049, 11, 31)
     *  })
     * });
     *
     * @section
     * <p>
     *  DatePicker will set the value only if the entered date is valid and
     *  within the defined range.
     * </p>
     * @section
     * <h3>Defining a Start View and Navigation Depth</h3>
     * <p>
     *  The first rendered view can be defined with "start" option.
     *  Navigation depth can be controlled with "depth" option. Predefined
     *  views are:
     * </p>
     * <ul>
     *  <li>"month" - shows the days from the month</li>
     *  <li>"year" - shows the months of the year</li>
     *  <li>"decade" - shows the years from the decade</li>
     *  <li>"century" - shows the decades from the century</li>
     * </ul>
     *
     * @exampleTitle Create a DatePicker for selecting a month
     * @example
     * $("#datePicker").kendoDatePicker({
     *  start: "year",
     *  depth: "year"
     * });
     *
     * @section
     * <h3>Accessing an Existing DatePicker</h3>
     * <p>
     *  You can reference an existing <b>DatePicker</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>.
     *  Once a reference has been established, you can use the API to control
     *  its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing DatePicker instance
     * @example
     * var datePicker = $("#datePicker").data("kendoDatePicker");

     * @name kendo.ui.AutoComplete.Description
     *
     * @section
     * <p>
     *  The <b>AutoComplete</b> provides suggestions depending on the typed
     *  text. It also allows multiple value entries. The suggestions shown by
     *  the <b>AutoComplete</b> can come from a local Array or from a remote
     *  data service.
     * </p>
     * <h3>Getting Started</h3>
     *
     * @exampleTitle Create a HTML input element
     * @example
     * <input id="autoComplete" />
     *
     * @exampleTitle Initialize the AutoComplete using a jQuery selector
     * @example
     * $(document).ready(function() {
     *  $("#autoComplete").kendoAutoComplete(["Item1", "Item2"]);
     * });
     *
     * @section <h3>AutoComplete Suggestions</h3>
     * <p>
     *  There are two primary ways to provide the <b>AutoComplete</b>
     *  suggestions:
     * </p>
     * <ol>
     *  <li>From a local array</li>
     *  <li>From a remote data service</li>
     * </ol>
     * <p>
     *  Locally defined values are best for small, fixed sets of suggestions.
     *  Remote suggestions should be used for larger data sets. When used
     *  with the <a href="../datasource/index.html">DataSource</a> component,
     *  filtering large remote data services can be pushed to the server as
     *  well, maximizing client-side performance.
     * </p>
     * <h3>Local Suggestions</h3>
     * <p>
     *  To configure and provide <b>AutoComplete</b> suggestions locally, you
     *  can either pass an array directly to its constructor or you can set
     *  the dataSource property to an local array.
     * </p>
     *
     * @exampleTitle Directly initialize suggestions in constructor
     * @example
     * $("#autoComplete").kendoAutoComplete(["Item1", "Item2", "Item3"]);
     *
     * @exampleTitle Using dataSource property to bind to local Array
     * @example
     * var data = ["Item1", "Item2", "Item3"];
     * $("#autoComplete").kendoAutoComplete({
     *    dataSource: data
     * });
     *
     * @section
     * <h3>Remote Suggestions</h3>
     * <p>
     *  The easiest way to bind an <b>AutoComplete</b> to remote
     *  suggestions is to use the
     *  <a href="../datasource/index.html">DataSource</a> component; an
     *  abstraction for local and remote data. The <b>DataSource</b>
     *  component can be used to serve data from a variety of data services,
     *  such as
     *  <a href="http://en.wikipedia.org/wiki/XML">XML</a>,
     *  <a href="http://en.wikipedia.org/wiki/JSON">JSON</a>, and
     *  <a href="http://en.wikipedia.org/wiki/JSONP">JSONP</a>.
     * </p>
     *
     * @exampleTitle Using the Kendo UI Web DataSource component to bind to
     * remote suggestions with OData
     * @example
     * $(document).ready(function(){
     *  $("#autoComplete").kendoAutoComplete({
     *   minLength: 3,
     *   dataTextField: "Name", // JSON property name to use
     *   dataSource: new kendo.data.DataSource({
     *    type: "odata", // specifies data protocol
     *    pageSize: 10, // limits result set

     *    }
     *   })

     * <p>
     *  You can reference an existing <b>AutoComplete</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>.

     * <p>
     *  A <strong>DropDownList</strong> displays a list of values and allows the selection of a single value from the
     *  list. It is a richer version of the standard HTML select, providing support for local and remote data binding,
     *  item templates, and configurable options for controlling the list behavior.
     * </p>
     * <p>
     *  If you want to allow user input, use the
     *  <a href="../dropdownlist/index.html" title="Kendo UI dropdownlist">Kendo UI dropdownlist</a>.
     * </p>
     * <h3>Getting Started</h3>
     * <p>There are two basic ways to create a <strong>DropDownList</strong>:</p>
     * <ol>
     *  <li>From a input element, using data binding to define the list items</li>
     *  <li>From a select element, using HTML to define the list items</li>
     * </ol>
     * <p>
     *  Regardless of the initialization technique, the resulting <strong>DropDownList</strong> will look and function
     *  identically.
     * </p>
     *
     * @exampleTitle Creating a dropdownlist from existing input HTML element
     * @example
     * <input id="dropDownList" />
     *
     * @section
     * <p></p>
     * <p>
     *  Initialization of a <strong>DropDownList</strong> should occur after the DOM is fully loaded. It is recommended
     *  that initialization the <strong>DropDownList</strong> occur within a handler is provided to
     *  $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize a DropDownList using a selector within $(document).ready()
     * @example
     * $(document).ready(function() {
     *     $("#dropDownList").kendoDropDownList({
     *         dataTextField: "text",
     *         dataValueField: "value",
     *         dataSource: [
     *             { text: "Item1", value: "1" },
     *             { text: "Item2", value: "2" }
     *         ]
     *     });
     * });
     *
     * @exampleTitle Create a DropDownList from existing select HTML element with a defined structure
     * @example
     * <select id="dropDownList">
     *     <option>Item 1</option>
     *     <option>Item 2</option>
     *     <option>Item 3</option>
     * </select>
     *
     * <script>
     *    $(document).ready(function(){
     *       $("#dropDownList").kendoDropDownList();
     *    });
     * </script>
     * @section
     * <h3>Binding to Data</h3>
     * <p>
     *  A <strong>DropDownList</strong> can be bound to both local arrays and remote data via the DataSource component.
     *  Arrays are appropriate for limited value options while remote data binding is better suited for larger data
     *  sets. With remote binding, options will be loaded on-demand, similar to an <strong>AutoComplete</strong>.
     * </p>
     *
     * @exampleTitle Binding to a remote OData service
     * @example
     * $(document).ready(function() {
     *     $("#titles").kendoDropDownList({
     *         index: 0,
     *         dataTextField: "Name",
     *         dataValueField: "Id",
     *         filter: "contains",
     *         dataSource: {
     *             type: "odata",

     * <h3>Customizing Item Templates</h3>
     * <p>
     *  A DropDownList leverages templates, providing an ability to control item rendering. For a complete overview of
     *  the template capabilities and syntax of Kendo UI Web, please review the
     *  <a href="../templates/index.html" title="Kendo UI Template">Kendo UI Template</a> demos and documentation.
     * </p>
     *
     * @exampleTitle Basic item template customization
     * @example
     * <!-- HTML -->
     * <input id="titles" />
     *
     * <!-- Template -->
     * <script id="scriptTemplate" type="text/x-kendo-template">
     *     # if (data.BoxArt.SmallUrl) { #
     *         <img src="${ data.BoxArt.SmallUrl }" alt="${ data.Name }" />Title:${ data.Name }, Year: ${ data.Name }

     *
     * @section
     * <p>
     * The <b>ComboBox</b> widget allows the selection from pre-defined
     * values or entering a new value. It is a richer version of the standard
     * HTML select, providing support for local and remote data binding, item
     * templates, and configurable options for controlling the list behavior.
     * </p>
     * <p>
     *  To prevent user input, use the
     *  <a href="../combobox/index.html">combobox</a>.
     * </p>
     * <h3>Getting Started</h3>
     * <p>There are two basic ways to create a <b>ComboBox</b>:</p>
     * <ol>
     *  <li>
     *   From a HTML input element, using data binding to define the list
     *   items
     *  </li>
     *  <li>
     *   From a HTML select element, using HTML to define the list items
     *  </li>
     * </ol>
     * <p>
     *  Regardless of the initialization technique, the resulting
     *  <b>ComboBox</b> will look and function identically.
     * </p>
     *
     * @exampleTitle Creating a combobox from existing input HTML element
     * @example
     * <input id="comboBox" />
     *
     * @exampleTitle ComboBox initialization
     * @example
     * $(document).ready(function(){
     *     $("#comboBox").kendoComboBox({
     *         dataTextField: "text",
     *         dataValueField: "value",
     *         dataSource: [
     *             { text: "Item1", value: "1" },
     *             { text: "Item2", value: "2" }
     *         ]
     *     });
     * });
     *
     * @exampleTitle Creating a ComboBox from existing select HTML element
     * @example
     * <select id="comboBox">
     *  <option>Item 1</option>
     *  <option>Item 2</option>
     *  <option>Item 3</option>
     * </select>
     *
     * <script>
     *    $(document).ready(function(){
     *      $("#comboBox").kendoComboBox();
     *    });
     * </script>
     *
     * @section
     * <h3>Binding to Data</h3>
     * <p>
     *  The <b>ComboBox</b> can be bound to both local arrays and remote data
     *  via the <a href="../datasource/index.html">DataSource</a> component;
     *  an abstraction for local and remote data. Local arrays are
     *  appropriate for limited value options, while remote data binding is
     *  better for larger data sets. With remote binding, options will be
     *  loaded on-demand, similar to an
     *  <a href="../combobox/index.html">combobox</a>.
     * </p>
     * @exampleTitle Binding to a remote OData service
     * @example
     * $(document).ready(function() {
     *  $("#comboBox").kendoComboBox({
     *   index: 0,
     *   dataTextField: "Name",
     *   dataValueField: "Id",
     *   filter: "contains",
     *   dataSource: {
     *    type: "odata",
     *    serverFiltering: true,
     *    serverPaging: true,
     *    pageSize: 20,
     *    transport: {
     *     read: "http://odata.netflix.com/Catalog/Titles"
     *    }
     *   }
     *  });
     * });
     *
     * @section
     * <h3>Customizing Item Templates</h3>
     * <p>
     *       ComboBox leverages Kendo UI high-performance Templates to give you complete control
     *       over item rendering. For a complete overview of Kendo UI Template capabilities and syntax,
     *       please review the <a href="../templates/index.html" title="Kendo UI Template">Kendo UI Template</a> demos and documentation.
     *   </p>
     * @exampleTitle Basic item template customization
     * @example
     * <input id="comboBox" />
     * <!-- Template -->
     * <script id="scriptTemplate" type="text/x-kendo-template">
     *  # if (data.BoxArt.SmallUrl) { #
     *  <img src="${ data.BoxArt.SmallUrl }" alt="${ data.Name }" />Title:${ data.Name }, Year: ${ data.Name }
     *  # } else { #

     *  # } #

     * <h3>Accessing an Existing ComboBox</h3>
     * <p>
     *  You can reference an existing <b>ComboBox</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>.
     *  Once a reference has been established, you can use the API to control
     *  its behavior.

     *  @name kendo.ui.Grid.Description
     *
     *  @section
     *  <p>
     *      The Grid widget displays tabular data and offers rich support interacting with data,
     *      including paging, sorting, grouping, and selection. Grid is a powerful widget with
     *      many configuration options. It can be bound to local JSON data or to remote data
     *      using the Kendo DataSource component.
     *  </p>
     *  <h3>Getting Started</h3>
     *  There are two primary ways to create a Kendo Grid:
     *
     *  <ol>
     *      <li>From an existing HTML table element, defining columns, rows, and data in HTML</li>
     *      <li>From an HTML div element, defining columns and rows with configuration, and binding to data</li>
     *  </ol>
     *
     *  @exampleTitle Creating a <b>Grid</b> from existing HTML Table element
     *  @example
     *  <!-- Define the HTML table, with rows, columns, and data -->
     *  <table id="grid">
     *   <thead>
     *       <tr>
     *           <th data-field="title">Title</th>
     *           <th data-field="year">Year</th>
     *       </tr>
     *   </thead>
     *   <tbody>
     *       <tr>
     *           <td>Star Wars: A New Hope</td>
     *           <td>1977</td>
     *       </tr>
     *       <tr>
     *           <td>Star Wars: The Empire Strikes Back</td>
     *           <td>1980</td>
     *       </tr>
     *   </tbody>
     *  </table>
     *
     *  @exampleTitle Initialize the Kendo Grid
     *  @example
     *   $(document).ready(function(){
     *       $("#grid").kendoGrid();
     *   });
     *
     *  @exampleTitle Creating a <b>Grid</b> from existing HTML Div element
     *  @example
     *  <!-- Define the HTML div that will hold the Grid -->
     *  <div id="grid">
     *  </div>
     *
     *  @exampleTitle Initialize the Kendo Grid and configure columns & data binding
     *  @example
     *    $(document).ready(function(){
     *       $("#grid").kendoGrid({
     *           columns:[
     *               {
     *                   field: "FirstName",
     *                   title: "First Name"
     *               },
     *               {
     *                   field: "LastName",
     *                   title: "Last Name"
     *           }],
     *           dataSource: {
     *               data: [
     *                   {
     *                       FirstName: "Joe",
     *                       LastName: "Smith"
     *                   },
     *                   {
     *                       FirstName: "Jane",
     *                       LastName: "Smith"
     *               }]
     *           }
     *       });
     *   });
     *
     *  @section <h3>Configuring Grid Behavior</h3>
     *  Kendo Grid supports paging, sorting, grouping, and scrolling. Configuring any of
     *  these Grid behaviors is done using simple boolean configuration options. For
     *  example, the follow snippet shows how to enable all of these behaviors.
     *
     *  @exampleTitle Enabling Grid paging, sorting, grouping, and scrolling
     *  @example
     *    $(document).ready(function(){
     *       $("#grid").kendoGrid({
     *          groupable: true,
     *          scrollable: true,
     *          sortable: true,
     *          pageable: true
     *       });
     *   });
     *  @section
     *  By default, paging, grouping, and sorting are <strong>disabled</strong>. Scrolling is enabled by default.
     *
     *  <h3>Performance with Virtual Scrolling</h3>
     *  When binding to large data sets or when using large page sizes, reducing active in-memory
     *  DOM objects is important for performance. Kendo Grid provides built-in UI virtualization
     *  for highly optimized binding to large data sets. Enabling UI virtualization is done via simple configuration.
     *
     *  @exampleTitle Enabling Grid UI virtualization
     *  @example
     *    $(document).ready(function(){
     *       $("#grid").kendoGrid({
     *          scrollable: {
     *              virtual: true
     *          }
     *       });
     *   });
     *
     * @section
     * <h3>Accessing an Existing Grid</h3>
     * <p>
     *  You can reference an existing <b>Grid</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>.
     *  Once a reference has been established, you can use the API to control
     *  its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing Grid instance
     * @example
     * var grid = $("#grid").data("kendoGrid");
     *

     * @name kendo.ui.NumericTextBox.Description
     *
     * @section
     * <p>
     *    The NumericTextBox widget can convert an INPUT element into a numeric, percentage or currency textbox.
     *    The type is defined depending on the specified format. The widget renders spin buttons and with their help you can
     *    increment/decrement the value with a predefined step. The NumericTextBox widget accepts only numeric entries.
     *    The widget uses <em>kendo.culture.current</em> culture in order to determine number precision and other culture
     *    specific properties.
     * </p>
     *
     * <h3>Getting Started</h3>
     *
     * @exampleTitle Creating a NumericTextBox from existing INPUT element
     * @example
     * <input id="textBox" />
     *
     * @exampleTitle NumericTextBox initialization
     * @example
     * $(document).ready(function(){
     *  $("#textBox").kendoNumericTextBox();
     * });
     *
     * @section
     * <p>
     *  When a <b>NumericTextBox</b> is initialized, it will automatically
     *  wraps the input element with span element and will render spin
     *  buttons.
     * </p>
     * <h3>Configuring NumericTextBox behaviors</h3>
     * <p>
     *  The <b>NumericTextBox</b> provides configuration options that can be
     *  easily set during initialization. Among the properties that can be
     *  controlled:
     * </p>
     * <ul>
     *  <li>Value of the <b>NumericTextBox</b></li>
     *  <li>Minimum and/or maximum values</li>
     *  <li>Increment step</li>
     *  <li>Precision of the number</li>
     *  <li>Number format (any valid number format is allowed)</li>
     * </ul>
     * <p>
     *  To see a full list of available properties and values, review the
     *  Slider Configuration API documentation tab.
     * </p>
     * @exampleTitle Customizing NumericTextBox defaults
     * @example
     *  $("#textbox").kendoNumericTextBox({
     *      value: 10,
     *      min: -10,
     *      max: 100,
     *      step: 0.75,
     *      format: "n",
     *      decimals: 3
     *  });
     * @section
     * @exampleTitle Create Currency NumericTextBox widget
     * @example
     *  $("#textbox").kendoNumericTextBox({
     *      format: "c2" //Define currency type and 2 digits precision
     *  });
     * @section
     * @exampleTitle Create Percentage NumericTextBox widget
     * @example
     *  $("#textbox").kendoNumericTextBox({
     *      format: "p",
     *      value: 0.15 // 15 %
     *  });
     *
     * @section
     * <h3>Accessing an Existing NumericTextBox</h3>
     * <p>
     *  You can reference an existing <b>NumericTextBox</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>.
     *  Once a reference has been established, you can use the API to control
     *  its behavior.

     *
     * @section
     * <p>
     *  The <b>Menu</b> displays hierarchical data as a multi-level menu. It provides rich styling for unordered lists
     *  of items, and can be used for both navigation and executing JavaScript commands. Items can be defined and
     *  initialized from HTML, or the API can be used to add and remove items.
     * </p>
     * <h3>Getting Started</h3>
     *
     * @exampleTitle Create a HTML hierarchical list of items
     * @example
     * <ul id="menu">
     *     <li>Item 1
     *         <ul>
     *             <li>Item 1.1</li>
     *             <li>Item 1.2</li>
     *         </ul>
     *     </li>
     *     <li>Item 2</li>
     * </ul>
     *
     * @section
     * <p>
     *  Initialization of a <strong>Menu</strong> should occur after the DOM is fully loaded. It is recommended that
     *  initialization the <strong>Menu</strong> occur within a handler is provided to $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize a Menu using a selector within $(document).ready()
     * @example
     * $(document).ready(function() {
     *     $("#menu").kendoMenu();
     * });
     *
     * @exampleTitle Initialize the Menu using JSON data object
     * @example
     * $(document).ready(function() {
     *  $("#menu").kendoMenu({
     *   dataSource: [
     *    {
     *     text: "Menu Item 1",
     *     items: [
     *      { text: "Sub Menu Item 1" },
     *      { text: "Sub Menu Item 2" }
     *     ]
     *    },
     *    {
     *     text: "Menu Item 2"
     *    }
     *   ]
     *  })
     * });
     *
     * @section
     * <h3>Customizing Menu Animations</h3>
     * <p>
     *  By default, the <b>Menu</b> uses a slide animation to expand and
     *  reveal sub-items as the mouse hovers. Animations can be easily
     *  customized using configuration properties, changing the animation
     *  style and delay. Menu items can also be configured to open on click
     *  instead of on hover.
     * </p>
     *
     * @exampleTitle Changing Menu animation and open behavior
     * @example
     * $("#menu").kendoMenu({
     *  animation: {
     *   open: { effects: "fadeIn" },
     *   hoverDelay: 500
     *  },
     *  openOnClick: true
     * });
     *
     * @section
     * <h3>Dynamically configuring Menu items</h3>
     * <p>
     *  The <b>Menu</b> API provides several methods for dynamically adding
     *  or removing Items. To add items, provide the new item as a JSON
     *  object along with a reference item that will be used to determine the
     *  placement in the hierarchy.
     * </p>
     * <p>
     *  A reference item is simply a target Menu Item HTML element that
     *  already exists in the Menu. Any valid jQuery selector can be used to
     *  obtain a reference to the target item. For examples, see the
     *  <a href="../menu/api.html" title="Menu API demos">Menu API demos</a>.
     *  Removing an item only requires a reference to the target element that
     *  should be removed.
     * </p>
     *
     * @exampleTitle Dynamically add a new root Menu item
     * @example
     * var menu = $("#menu").kendoMenu().data("kendoMenu");
     * menu.insertAfter(
     *  { text: "New Menu Item" },
     *  menu.element.children("li:last")
     * );
     *
     * @section
     * <h3>Accessing an Existing Menu</h3>
     * <p>
     *  You can reference an existing <b>Menu</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>.
     *  Once a reference has been established, you can use the API to control
     *  its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing Menu instance
     * @example
     * var menu = $("#menu").data("kendoMenu");

     * @name kendo.ui.PanelBar.Description
     *
     * @section
     * <p>
     *  The <strong>PanelBar</strong> displays hierarchical data as a multi-level, expandable widget that is useful for
     *  constained areas of a page. Its structure may be defined in HTML or configured dynamically through its API. The
     *  content for items can also be loaded via AJAX by specifying a content URL.
     * </p>
     * <h3>Getting Started</h3>
     * <p>
     *  A <strong>PanelBar</strong> can be created by targeting the root element of a HTML list. A
     *  <strong>PanelBar</strong> will utilize this list to define its structure and content.
     * </p>
     *
     * @exampleTitle Create a list of items
     * @example
     * <ul id="panelBar">
     *     <li>
     *         Item 1
     *             <ul>
     *                 <li>Sub Item 1</li>
     *                 <li>Sub Item 2</li>
     *             </ul>
     *     <li>
     *     <li>Item 2</li>
     * </ul>
     *
     * @section
     * <p></p>
     * <p>
     *  Initialization of a <strong>PanelBar</strong> should occur after the DOM is fully loaded. It is recommended
     *  that initialization the <strong>PanelBar</strong> occur within a handler is provided to $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize the PanelBar via an ID selector
     * @example
     * $(document).ready(function() {
     *     $("#panelBar").kendoPanelBar();
     * });
     *
     * @section
     * <p>
     *  <strong>PanelBar</strong> items may contain nested content (including markup) within a <strong>div</strong>
     *  element. Text content located outside nested content will be used as the title of the item.
     * </p>
     *
     * @exampleTitle Create a list of items in HTML with nested content
     * @example
     * <ul id="panelBar">
     *     <li>Item with no content</li>
     *     <li>Item with content
     *         <div>This is nested content of a PanelBar item.</div>
     *     </li>
     * </ul>
     *
     * @section
     * <p>A <strong>PanelBar</strong> will preserve the content defined within an item.</p>
     *
     * @exampleTitle Initialize the PanelBar via an ID selector
     * @example
     * var panelBar = $("#panelbar").kendoPanelBar();
     *
     * @exampleTitle Initialize a PanelBar using JSON data object
     * @example
     * $("#panelbar").kendoPanelBar({
     *     dataSource: [
     *         {
     *             text: "Item 1",
     *             items: [
     *                 { text: "Sub Item 1" },
     *                 { text: "Sub Item 2" }
     *             ]
     *         },
     *         { text: "Item 2" }
     *     ]
     * });
     *
     * @section
     * <h3>Loading Content with AJAX</h3>
     * <p>
     *  While any valid technique for loading AJAX content can be used, the <strong>PanelBar</strong> provides built-in
     *  support for asynchronously loading content from URLs. These URLs should return HTML fragments that can be
     *  loaded in the <strong>PanelBar</strong> item content area.
     * </p>
     *
     * @exampleTitle Create a list of items with a target for dynamic content
     * @example
     * <ul id="panelBar">
     *     <li>Item 1
     *         <ul>
     *             <li>Sub Item 1</li>
     *         </ul>
     *     </li>
     *     <li>Item 2</li>
     *     <li>
     *         Item with Dynamic Content
     *         <div></div>
     *     </li>
     * </ul>
     *
     * @exampleTitle Load a PanelBar item content asynchronously via AJAX
     * @example
     * $("#panelBar").kendoPanelBar({
     *     contentUrls:[
     *         null,
     *         null,
     *         "html-content-snippet.html"
     *     ]
     * });
     *
     * @section
     * <p>
     *  When the <strong>PanelBar</strong> loads remote content via AJAX, the server response is cached in-memory so
     *  that subsequent expand/collapse actions do not trigger subsequent AJAX requests.
     * </p>
     * <h3>Customizing PanelBar Animations</h3>
     * <p>
     *  By default, a <strong>PanelBar</strong> uses animations to expand and reveal sub-items when an item header is
     *  clicked. These animations can be modified in configuration via the open and close animation properties. A
     *  <strong>PanelBar</strong> can also be configured to only allow one panel to remain open at a time.
     * </p>
     *
     * @exampleTitle Changing PanelBar animation and expandMode behavior
     * @example
     * $("#panelBar").kendoPanelBar({
     *     animation: {
     *         open : { effects: "fadeIn" }
     *     },
     *     expandMode: "single"
     * });
     *
     * @section
     * <h3>Dynamically Configuring PanelBar Items</h3>
     * <p>
     *  The <strong>PanelBar</strong> API provides several methods for dynamically adding or removing Items. To add
     *  items, provide the new item as a JSON object along with a reference item that will be used to determine its
     *  placement in the items hierarchy. Note: The reference item is optional when appending.
     * </p>
     * <p>
     *  A reference item is a target <strong>PanelBar</strong> item HTML element that already exists in the PanelBar.
     *  Any valid selector can be used to obtain a reference to the target item.
     * </p>
     * <p>Removing an item only requires a reference to the target element that should be removed.</p>
     *
     * @exampleTitle Dynamically adding a new root PanelBar item
     * @example
     * var panelBar = $("#panelBar").kendoPanelBar().data("kendoPanelBar");
     *
     * panelBar.insertAfter(
     *      { text: "New PanelBar Item" },
     *      panelBar.element.children("li:last")
     * );
     *
     * @section
     * <h3>Accessing an Existing PanelBar</h3>
     * <p>
     *  You can reference an existing <strong>PanelBar</strong> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>. Once a reference has been established, you can
     *  use the API to control its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing PanelBar instance
     * @example
     * var panelBar = $("#panelBar").data("kendoPanelBar");

     *  each tab.

     * @exampleTitle Create an unordered list for tabs with associated div elements for content
     * @example
     * <div id="tabStrip">
     *     <ul>
     *         <li>First tab</li>
     *         <li>Second tab</li>

     * <p>
     *  Initialization of a <strong>TabStrip</strong> should occur after the DOM is fully loaded. It is recommended
     *  that initialization the <strong>TabStrip</strong> occur within a handler is provided to $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize a TabStrip using a selector within $(document).ready()
     * @example

     *  While any valid technique for loading AJAX content can be used, a <strong>TabStrip</strong> supports loading

     * <h3>Dynamically Configure TabStrip Tabs</h3>
     * <p>
     *  The <strong>TabStrip</strong> API provides several methods for dynamically adding or removing tabs. To add
     *  tabs, provide the new item as a JSON object along with a reference item that will be used to determine the
     *  placement in the <strong>TabStrip</strong>. Note: append() does not require a reference item.
     * <p>
     * <p>
     *  A reference item is simply a target DOM element of a tab that already exists in the TabStrip. Any valid
     *  selector may be used to obtain a reference to the target item.
     * </p>
     * <p>Removing an item requires a reference to the target element.</p>

     * <h3>Selecting a Tab on Initial Load</h3>
     * <p>
     *  It is possible to select a tab and display its associated content upon its initial load. There are two (2) ways
     *  to accomplish this task:
     * </p>
     * <ol>
     *  <li>Add a "k-state-active" class to the DOM element of the tab</li>
     *  <li>Use select() to target and select a tab either by selector or index</li>
     * </ol>
     * <p>Both approaches produce the same result.</p>
     *
     * @exampleTitle Selecting a default tab manually using HTML
     * @example
     * <div id="tabstrip">
     *     <ul>
     *         <li class="k-state-active">First Tab</li>
     *         <li>Second Tab</li>
     *     </ul>

     * @name kendo.ui.TimePicker.Description
     *
     * @section
     * <p>
     *  The <strong>TimePicker</strong> allows the end user to select a time value from a list of predefined values or
     *  to type a new value. It supports configurable options for the format, minimum and maximum time, and the
     *  interval between predefined values in the list.
     * </p>
     * <h3>Getting Started</h3>
     *
     * @exampleTitle Creating a TimePicker from existing input element
     * @example
     * <input id="timePicker" />
     *
     * @exampleTitle Initialize the PanelBar via an ID selector
     * @example
     * $(document).ready(function(){
     *     $("#timePicker").kendoTimePicker();
     * });
     *
     * @section
     * <p>
     *  When a <strong>TimePicker</strong> is initialized, it will automatically be displayed near the location of the
     *  used HTML element.
     * </p>
     * <h3>Configuring TimePicker Behaviors</h3>
     * <p>
     *  A <strong>TimePicker</strong> provides configuration options that can be easily set during initialization.
     *  Among the properties that can be controlled:
     * </p>
     * <ul>
     *  <li>Selected time</li>
     *  <li>Minimum/Maximum time</li>
     *  <li>Define format</li>
     *  <li>Define interval between predefined values in the list</li>
     * </ul>
     *
     * @exampleTitle Create TimePicker with selected time and defined min and max time
     * @example
     * $("#timePicker").kendoTimePicker({
     *     value: new Date(2000, 10, 10, 10, 0, 0),
     *     min: new Date(1950, 0, 1, 8, 0, 0),
     *     max: new Date(2049, 11, 31, 18, 0, 0)
     * });
     *
     * @section
     * <p>
     *  A <strong>TimePicker</strong> will set the value only if the entered time is valid and if it is in the defined
     *  range.
     * </p>
     *
     * @exampleTitle Define time format
     * @example
     * $("#timePicker").kendoTimePicker({
     *     format: "hh:mm:ss tt"
     * });
     *
     * @exampleTitle Define the interval (in minutes) between values in the list
     * @example
     * $("#timePicker").kendoTimePicker({
     *     interval: 15
     * });
     *
     * @section
     * <h3>Accessing an Existing TimePicker</h3>
     * <p>
     *  You can reference an existing <strong>TimePicker</strong> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>. Once a reference has been established, you can
     *  use the API to control its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing TimePicker instance
     * @example
     * var timePicker = $("#timePicker").data("kendoTimePicker");

     *
     * @section
     * <p>
     *  The <strong>TreeView</strong> displays hierarchical data in a traditional tree structure. It supports user
     *  interaction through the mouse or touch to perform re-ordering operations via drag-and-drop.
     * </p>
     * <p>
     *  A <strong>TreeView</strong> can be created by leveraging HTML lists. However, it does not support binding to a
     *  remote data source at this point in time.
     * </p>
     * <h3>Getting Started</h3>
     * <p>A <strong>TreeView</strong> can be created in two ways:</p>
     * <ol>
     *  <li>Define a hierarchical list with static HTML</li>
     *  <li>Use dynamic data binding</li>
     * </ol>
     * <p>
     *  Static HTML definition is appropriate for small hierarchies and for data that does not change frequently.
     *  Databinding should be used for larger data sets and for data that changes frequently.
     * </p>
     * <h3>Creating a TreeView from HTML</h3>
     *
     * @exampleTitle Create a hierarchical list in HTML
     * @example
     * <ul id="treeView">
     *     <li>Item 1
     *         <ul>
     *             <li>Item 1.1</li>
     *             <li>Item 1.2</li>
     *         </ul>
     *     </li>
     *     <li>Item 2</li>
     * </ul>
     *
     * @section
     * <p>
     *  Initialization of a <strong>TreeView</strong> should occur after the DOM is fully loaded. It is recommended
     *  that initialization the <strong>TreeView</strong> occur within a handler is provided to $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize a TreeView using a selector within $(document).ready()
     * @example
     * $(document).ready(function() {
     *     $("#treeView").kendoTreeView();
     * });
     *
     * @section
     * <h3>Creating a TreeView with Data Binding to a Local Data Source</h3>
     *
     * @exampleTitle Create a hierarchical HTML list
     * @example
     * <div id="treeView"></div>
     *
     * @exampleTitle Initialize and bind the TreeView
     * @example
     * $(document).ready(function() {
     *     $("#treeView").kendoTreeView({
     *         dataSource: [
     *             {
     *                 text: "Item 1",
     *                 items: [
     *                     { text: "Item 1.1" },
     *                     { text: "Item 1.2" }
     *                 ]
     *             },
     *             { text: "Item 2" }
     *         ]
     *     })
     * });
     *
     * @section
     * <p>Currently, the <strong>TreeView</strong> does not support binding to a remote data source.</p>
     * @exampleTitle TreeView item JSON structure
     * @example
     * var item = {
     *     text: "Item text",
     *     imageUrl: "/images/icon.png", // renders a <img class="k-image" src="/images/icon.png" />
     *     spriteCssClass: "icon save",  // renders a <span class="k-sprite icon save" />
     *     items: [
     *         // child items
     *     ]
     * }
     *
     * @section
     * <h3>Configuring TreeView Behavior</h3>
     * <p>
     *  A number of <strong>TreeView</strong> behaviors can be easily controlled by simple configuration properties,
     *  such as animation behaviors and drag-and-drop behaviors.
     * </p>
     *
     * @exampleTitle Enabling drag-and-drop for TreeView nodes
     * @example
     * $("#treeView").kendoTreeView({
     *     dragAndDrop: true
     * });
     *
     * @section
     * <p>
     *  When drag-and-drop is enabled, the nodes of a <strong>TreeView</strong> can be dragged and dropped between all
     *  levels, with useful tooltips helping indicate where the node will be dropped.
     * </p>
     * <h3>Accessing an Existing TreeView</h3>
     * <p>
     *  You can reference an existing <strong>TreeView</strong> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>. Once a reference has been established, you can
     *  use the API to control its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing TreeView instance
     * @example
     * var treeView = $("#treeView").data("kendoTreeView");

 * @fileOverview Provides a Slider and RangeSlider implementation which can be used to display a rich input for
 * selecting values or ranges of values.

    /**
     *
     * @name kendo.ui.Slider.Description
     *
     * @section
     * <p>
     *  The <strong>Slider</strong> provides a rich input for selecting values or ranges of values. Unlike the HTML5
     *  range input, the <strong>Slider</strong> presents a consistent experience across browsers and features a rich
     *  API and event model.
     * </p>
     * <h3>Getting Started</h3>
     * <p>There are two types of <strong>Slider</strong>:</p>
     * <ol>
     *  <li><strong>Slider</strong>, which presents one thumb and two opposing buttons for selecting a single value</li>
     *  <li><strong>RangeSlider</strong>, which present two thumbs for defining a range of values</li>
     * </ol>
     * <h4>Slider</h4>
     *
     * @exampleTitle Create an input element
     * @example
     * <input id="slider" />
     *
     * @section
     * <p>
     *  Initialization of a <strong>Slider</strong> should occur after the DOM is fully loaded. It is recommended that
     *  initialization the <strong>Slider</strong> occur within a handler is provided to $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize a Slider using a selector within $(document).ready()
     * @example
     * $(document).ready(function() {
     *     $("#slider").kendoSlider();
     * });
     *
     * @section
     * <h4>RangeSlider</h4>
     * @exampleTitle Create two HTML input elements in a div
     * @example
     * <div id="rangeSlider">
     *     <input />
     *     <input />
     * </div>
     *
     * @section
     * <p>
     *  Initialization of a <strong>RangeSlider</strong> should occur after the DOM is fully loaded. It is recommended
     *  that initialization the <strong>RangeSlider</strong> occur within a handler is provided to $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize a RangeSlider using a selector within $(document).ready()
     * @example
     * $(document).ready(function() {
     *     $("#rangeSlider").kendoRangeSlider();
     * });
     *
     * @section
     * <p>
     *  The <strong>RangeSlider</strong> requires two inputs to capture both ends of the value range. This benefits
     *  scenarios where JavaScript is disabled, in which case users will be presented with two inputs, still allowing
     *  them to input a valid range.
     * </p>
     * <h3>Customizing Slider Behaviors</h3>
     * <p>
     *  Many facets of the <strong>Slider</strong> and <strong>RangeSlider</strong> behavior can be configured through
     *  properties, including:
     * </p>
     * <ul>
     *  <li>Minimum and/or maximum values</li>
     *  <li>Orientation (horizontal or vertical)</li>
     *  <li>Small or large step</li>
     *  <li>Tooltip format/placement</li>
     * </ul>
     *
     * @exampleTitle Initialize a Slider and its properties
     * @example
     * $("#slider").kendoSlider({
     *     min: 10,
     *     max: 50,
     *     orientation: "vertical",
     *     smallStep: 1,
     *     largeStep: 10
     * });
     *
     * @section
     * <h3>Accessing an Existing Slider</h3>
     * <p>
     *  You can reference an existing <strong>Slider</strong> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>. Once a reference has been established, you can
     *  use the API to control its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing Slider instance
     * @example
     * var slider = $("#slider").data("kendoSlider");

/**
 * @fileOverview Provides a Splitter implementation which can be used to display a dynamic layout of resizable and
 * collapsible panes.

    /**
     * @name kendo.ui.Splitter.Description
     *
     * @section
     * <p>
     *  The <strong>Splitter</strong> provides a dynamic layout of resizable and collapsible panes. It converts the
     *  children of an HTML element in to the interactive layout, adding resize and collapse handles based on
     *  configuration. A <strong>Splitter</strong> can be mixed in a vertical or horizontal orientation to build
     *  complex layouts.
     * </p>
     * <h3>Getting Started</h3>
     * <p>
     *  The layout and structure of a <strong>Splitter</strong> is defined within the DOM as a div with child elements.
     * </p>
     *
     * @exampleTitle Create a div with children that will become panes
     * @example
     * <div id="splitter">
     *     <div>Area 1</div>
     *     <div>Area 2</div>
     * </div>
     *
     * @section
     * <p>
     *  Initialization of a <strong>Splitter</strong> should occur after the DOM is fully loaded. It is recommended
     *  that initialization the <strong>Splitter</strong> occur within a handler is provided to $(document).ready().
     * </p>
     *
     * @exampleTitle Initialize the Splitter using a selector within $(document).ready()
     * @example
     * $(document).ready(function() {
     *     $("#splitter").kendoSplitter();
     * });
     *
     * @section
     * <p>
     *  When the <strong>Splitter</strong> is initialized, a vertical split bar will be placed between the two div
     *  elements. This bar can be moved by a user left and right to adjust the size on the panes.
     * </p>
     * <h3>Configuring Splitter Behaviors</h3>
     * <p>
     *  The <strong>Splitter</strong> has a default configuration specified during initialization. However, these
     *  options may be overriden to control the following properties:
     * </p>
     * <ul>
     *  <li>Maximum and/or minimum pane sizes</li>
     *  <li>Resizable and collapsible/expandable pane behaviors</li>
     *  <li>Orientation (horizontal or vertical)</li>
     * </ul>
     * <p>
     *  The properties of a pane must be set during initialization and set for each individual pane in a
     *  <strong>Splitter</strong>.
     * </p>
     *
     * @exampleTitle Initialize a Splitter and the properties of its panes
     * @example
     * $("#splitter").kendoSplitter({
     *     panes: [
     *         { collapsible: true, min: "100px", max: "300px" },
     *         { collapsible: true }
     *     ],
     *     orientation: "vertical"
     * });
     *
     * @section
     * <h3>Nested Splitter Layouts</h3>
     * <p>To achieve complex layouts, the <strong>Splitter</strong> supports nested layouts.</p>
     *
     * @exampleTitle Creating nested Splitter layout
     * @example
     * <div id="horizontalSplitter">
     *     <div><p>Left Side Pane Content</p></div>
     *     <div>
     *         <div id="verticalSplitter">
     *             <div><p>Right Side, Top Pane Content</p></div>
     *             <div><p>Right Side, Bottom Pane Content</p></div>
     *         </div>
     *     </div>
     * </div>
     *
     * @exampleTitle Initialize two Splitters with differing orientations
     * @example
     * $("horizontalSplitter").kendoSplitter();
     * $("verticalSplitter").kendoSplitter({ orientation: "vertical" });
     *
     * @section
     * <h3>Loading Content with AJAX</h3>
     * <p>
     *  While any valid technique for loading content via AJAX may be used, <strong>Splitter</strong> provides built-in
     *  support for asynchronously loading content from URLs. These URLs should return HTML fragments that can be
     *  loaded in the pane of a <strong>Splitter</strong>. If you want to load a whole page in an IFRAME, you may do so
     *  by specifying the complete URL (i.e. http://kendoui.com/).
     * </p>
     *
     * @exampleTitle Loading Splitter content asynchronously
     * @example
     * <div id="splitter">
     *     <div>Area 1 with Static Content</div>
     *     <div></div>
     *     <div></div>
     * </div>
     *
     * @exampleTitle Initialize Splitter; configure async loading for one pane; and an iframe for a third pane
     * @example
     * $(document).ready(function() {
     *     $("#splitter").kendoSplitter({
     *         panes: [
     *             {},
     *             { contentUrl: "html-content-snippet.html" },
     *             { contentUrl: "http://kendoui.com/" }
     *         ]
     *     });
     * });
     *
     * @section
     * <h3>Accessing an Existing Splitter</h3>
     * <p>
     *  You can reference an existing <strong>Splitter</strong> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>. Once a reference has been established, you can
     *  use the API to control its behavior.
     * </p>
     *
     * @exampleTitle Accessing an existing Splitter instance
     * @example
     * var splitter = $("#splitter").data("kendoSplitter");

     *
     * @section
     * <p>
     *  An <strong>Upload</strong> uses progressive enhancement to deliver the best possible uploading experience to
     *  users without requiring extra developer effort. Features highlights:
     * </p>
     * <ul>
     *  <li>Asynchronous and synchronous (on form submit) file upload</li>
     *  <li>Multiple file selection</li>
     *  <li>Removing uploaded files</li>
     *  <li>Progress tracking *</li>
     *  <li>File drag-and-drop *</li>
     *  <li>Cancelling upload in-progress *</li>
     * </ul>
     * <p>(*) These features are automatically enabled if supported by the browser.</p>
     * <p>An <strong>Upload</strong> is a standards-based widget; no plug-ins required.</p>
     * <h3>Getting Started</h3>
     *
     * @exampleTitle 1. Create a simple HTML form and input element of type "file"
     * @example
     * <!-- Kendo will automatically set the form enctype attribute to "multi-part/form-data" -->
     * <form method="post" action="handler.php">
     *     <div>
     *         <input name="photos[]" id="photos" type="file" />
     *     </div>
     * </form>
     *
     * @exampleTitle 2. Initialize Upload with a jQuery selector
     * @example
     * $(document).ready(function() {
     *     $("#photos").kendoUpload();
     * });
     *
     * @section
     * <p>
     *  Note the array syntax in the input name; it is used to hint the upload handler to treat photos as an array.
     * </p>
     * <p>
     *  Please consult the documentation of your specific server technology regarding the handling of uploaded files.
     * </p>

     * <h3>Accessing an Existing Upload</h3>
     * <p>
     *  You can reference an existing <b>Upload</b> instance via
     *  <a href="http://api.jquery.com/jQuery.data/">jQuery.data()</a>. Once a reference has been established, you can
     *  use the API to control its behavior.

    /**
     * @name kendo.ui.Window.Description
     *
     * @section
     * <p>
     *  A <strong>Window</strong> displays content in a modal or non-modal HTML window. By default, a
     *  <strong>Window</strong> can be moved, resized, and closed. Its content can also be defined with either as
     *  static HTML or loaded dynamically via AJAX.
     * </p>
     * <p>
     *  A <strong>Window</strong> can be initialized from virtually any DOM element. During initialization, the
     *  targeted content will automatically be wrapped in the div element of the <strong>Window</strong>.
     * </p>
     * <h3>Getting Started</h3>
     *
     * @exampleTitle Create a simple HTML element with the Window content
     * @example
     * <div id="window">
     *     Content of the Window
     * </div>
     *
     * @exampleTitle Initialize the Window using a selector
     * @example
     * $(document).ready(function() {
     *     $("#window").kendoWindow();
     * });
     *
     * @section
     * <p>
     *  When a <strong>Window</strong> is initialized, it will automatically be displayed open near the location of the
     *  DOM element that was used to initialize the content.
     * </p>
     * <h3>Configuring Window Behaviors</h3>
     * <p>
     *  A <strong>Window</strong> provides many configuration options that can be easily set during initialization.
     *  Among the properties that can be controlled:
     * </p>
     * <ul>
     *  <li>Minimum height/width</li>
     *  <li>Available user actions (close/refresh/maximize/minimize)</li>
     *  <li>Title</li>
     *  <li>Draggable and resizable behaviors</li>
     * </ul>
     *
     * @exampleTitle Create a modal Window with all user actions enabled
     * @example
     * $("#window").kendoWindow({
     *     actions: ["Refresh", "Maximize", "Minimize", "Close"],
     *     draggable: false,
     *     height: "300px",
     *     modal: true,
     *     resizable: false,
     *     title: "Modal Window",
     *     width: "500px"
     * });
     *
     * @section
     * <p>
     *  The order of the values in the actions array determines the order in which the action buttons will be rendered
     *  in the title of a <strong>Window</strong>. The maximize action serves both as a button for expanding a
     *  <strong>Window</strong> to fill the screen and as a button to restore a <strong>Window</strong> to its previous
     *  size. The minimize action collapses a <strong>Window</strong> to its title.
     * </p>
     * <h3>Positioning and Opening a Window</h3>
     * <p>
     *  In some scenarios, it is preferable to center a <strong>Window</strong> rather than open it near the HTML
     *  element used to define the content. It is also common to open a <strong>Window</strong> as the result of the
     *  action of a user rather than on the load event of a page. The <strong>Window</strong> API provides methods for
     *  handling these scenarios.
     * </p>
     *
     * @exampleTitle Centering a Window and opening on button click
     * @example
     * <p id="window">
     *     Content of the Window
     * </p>
     * <button id="openButton">Open Window</button>
     *
     * @exampleTitle Initialize Window, center, and configure button click action
     * @example
     * $(document).ready(function(){
     *     var window = $("#window").kendoWindow({
     *         height: "200px",
     *         title: "Centered Window",
     *         visible: false,
     *         width: "200px"
     *     }).data("kendoWindow");
     * });
     *
     * $("#openButton").click(function(){
     *     var window = $("#window").data("kendoWindow");
     *     window.center();
     *     window.open();
     * });
     *
     * @section
     * <h3>Loading Window content via AJAX</h3>
     * <p>
     *  A <strong>Window</strong> provides built-in support for asynchronously loading content from a URL. This URL
     *  should return a HTML fragment that can be loaded in a Window content area.
     * </p>
     *
     * @exampleTitle Load Window content asynchronously
     * @example
     * <div id="window"></div>
     *
     * @exampleTitle Initialize window and configure content loading
     * @example
     * $(document).ready(function(){
     *     $("#window").kendoWindow({
     *         content: "html-content-snippet.html",
     *         title: "Async Window Content"
