Used for rendering the navigation item of the Calendar. To define the navigation item template, nest an <ng-template>
tag with the kendoCalendarNavigationItemTemplate directive inside the component tag. The template context is set to the
current component. To get a reference to the current item value, use the let-title directive. To provide more details
about the current title, get a reference to the current date by using the let-date='date' directive or get a reference
to the current active view by using the let-activeView='activeView' directive.
