/**
 * Elgg navigation library
 * Functions for managing menus and other navigational elements
 *
 * Breadcrumbs
 * Elgg uses a breadcrumb stack. The page handlers (controllers in MVC terms)
 * push the breadcrumb links onto the stack. @see elgg_push_breadcrumb()
 *
 *
 * Pagination
 * Automatically handled by Elgg when using elgg_list_entities* functions.
 * @see elgg_list_entities()
 *
 *
 * Tabs
 * @see navigation/tabs view
 *
 *
 * Menus
 * Elgg uses a single interface to manage its menus. Menu items are added with
 * {@link elgg_register_menu_item()}. This is generally used for menus that
 * appear only once per page. For dynamic menus (such as the hover
 * menu for user's avatar), a plugin hook is emitted when the menu is being
 * created. The hook is 'register', 'menu:<menu_name>'. For more details on this,
 * @see elgg_view_menu().
 *
 * Menus supported by the Elgg core
 * Standard menus:
 *     site   Site navigation shown on every page.
 *     page   Page menu usually shown in a sidebar. Uses Elgg's context.
 *     topbar Topbar menu shown on every page. The default has two sections.
 *     footer Like the topbar but in the footer.
 *     extras Links about content on the page. The RSS link is added to this.
 *
 * Dynamic menus (also called just-in-time menus):
 *     user_hover  Avatar hover menu. The user entity is passed as a parameter.
 *     entity      The set of links shown in the summary of an entity.
 *     river       Links shown on river items.
 *     owner_block Links shown for a user or group in their owner block.
 *     filter      The tab filter for content (all, mine, friends)
 *     title       The buttons shown next to a content title.
 *     longtext    The links shown above the input/longtext view.
 *     login       Menu of links at bottom of login box
 *
 * @package    Elgg.Core
 * @subpackage Navigation
