/**
* XListMenu class
*
* XListMenu displays a list of hyperlinks that can be used for page menus.
* Menu items adjust their css class automatically according to the current
* page displayed. In particular, a menu item is considered as active if
* the URL it represents is for the page currently displayed.
*
* Usage of XListMenu is similar to PRADO list controls. Each list item has
* two extra properties: {@link XListMenuItem::setPagePath PagePath} and
* {@link XListMenuItem::setNavigateUrl NavigateUrl}. The former is used to
* determine if the item is active or not, while the latter specifies the
* URL for the item. If the latter is not specified, a URL to the page is
* generated automatically.
*
* In template, you may use the following tags to specify a menu:
* <code>
* <com:XListMenu ActiveCssClass="class1" InactiveCssClass="class2">
* <com:XListMenuItem Text="Menu 1" PagePath="Page1" />
* <com:XListMenuItem Text="Menu 2" PagePath="Page2" NavigateUrl="/page2" />
* </com:XListMenu>
* </code>
