+/**
+ * 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');
+ *
+ * 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>
