An GridViewItemContainerGenerator is responsible for generating the UI on behalf of its host (e.g. BaseItemsControl). It maintains the association between the items in the control's data view and the corresponding UIElements. The control's item-host can ask the GridViewItemContainerGenerator for a Generator, which does the actual generation of UI.
