* TRepeaterItemRenderer class
*
* TRepeaterItemRenderer can be used as a convenient base class to
* define an item renderer class for {@link TRepeater}.
*
* Because TRepeaterItemRenderer extends from {@link TTemplateControl}, derived child classes
* can have templates to define their presentational layout.
*
* TRepeaterItemRenderer implements {@link IItemDataRenderer} interface,
* which enables the following properties that are related with data-bound controls:
* - {@link getItemIndex ItemIndex}: zero-based index of this control in the repeater item collection.
* - {@link getItemType ItemType}: item type of this control, such as TListItemType::AlternatingItem
* - {@link getData Data}: data associated with this control
* @author Qiang Xue <qiang.xue@gmail.com>
* @version $Id$
