/**
 * Class TAccordion.
 *
 * TAccordion displays an accordion control. Users can click on the view headers to switch among
 * different accordion views. Each accordion view is an independent panel that can contain arbitrary content.
 *
 * A TAccordion control consists of one or several {@link TAccordionView} controls representing the possible
 * accordion views. At any time, only one accordion view is visible (active), which is specified by any of
 * the following properties:
 * - {@link setActiveViewIndex ActiveViewIndex} - the zero-based integer index of the view in the view collection.
 * - {@link setActiveViewID ActiveViewID} - the text ID of the visible view.
 * - {@link setActiveView ActiveView} - the visible view instance.
 * If both {@link setActiveViewIndex ActiveViewIndex} and {@link setActiveViewID ActiveViewID}
 * are set, the latter takes precedence.
 *
 * TAccordion uses CSS to specify the appearance of the accordion headers and panel. By default,
 * an embedded CSS file will be published which contains the default CSS for TTabPanel.
 * You may also use your own CSS file by specifying the {@link setCssUrl CssUrl} property.
 * The following properties specify the CSS classes used for elements in a TAccordion:
 * - {@link setCssClass CssClass} - the CSS class name for the outer-most div element (defaults to 'accordion');
 * - {@link setHeaderCssClass HeaderCssClass} - the CSS class name for nonactive accordion div elements (defaults to 'accordion-header');
 * - {@link setActiveHeaderCssClass ActiveHeaderCssClass} - the CSS class name for the active accordion div element (defaults to 'accordion-header-active');
 * - {@link setViewCssClass ViewCssClass} - the CSS class for the div element enclosing view content (defaults to 'accordion-view');
 *
 * When the user clicks on a view header, the switch between the old visible view and the clicked one is animated.
 * You can use the {@link setAnimationDuration AnimationDuration} property to set the animation length in seconds;
 * it defaults to 1 second, and when set to 0 it will produce an immediate switch with no animation.
 *
 * The TAccordion auto-sizes itself to the largest of all views, so it can encompass all of them without scrolling.
 * If you want to specify a fixed height (in pixels), use the {@link setViewHeight ViewHeight} property.
 * When a TAccordion is nested inside another, it's adviced to manually specify a {@link setViewHeight ViewHeight} for the internal TAccordion
 *
 * To use TAccordion, write a template like following:
 * <code>
 * <com:TAccordion>
 *   <com:TAccordionView Caption="View 1">
 *     content for view 1
 *   </com:TAccordionView>
 *   <com:TAccordionView Caption="View 2">
 *     content for view 2
 *   </com:TAccordionView>
 *   <com:TAccordionView Caption="View 3">
 *     content for view 3
 *   </com:TAccordionView>
 * </com:TAccordion>
 * </code>
