/**
* Render a menu
*
* @see elgg_register_menu_item() for documentation on adding menu items and
* navigation.php for information on the different menus available.
*
* This function triggers a 'register', 'menu:<menu name>' plugin hook that enables
* plugins to add menu items just before a menu is rendered. This is used by
* dynamic menus (menus that change based on some input such as the user hover
* menu). Using elgg_register_menu_item() in response to the hook can cause
* incorrect links to show up. See the blog plugin's blog_owner_block_menu()
* for an example of using this plugin hook.
*
* An additional hook is the 'prepare', 'menu:<menu name>' which enables plugins
* to modify the structure of the menu (sort it, remove items, set variables on
* the menu items).
*
* elgg_view_menu() uses views in navigation/menu
*
* @param string $menu_name The name of the menu
* @param array $vars An associative array of display options for the menu.
* Options include:
* sort_by => string or php callback
* string options: 'name', 'priority', 'title' (default),
* 'register' (registration order) or a
* php callback (a compare function for usort)
* handler: string the page handler to build action URLs
* entity: ElggEntity to use to build action URLs
* class: string the class for the entire menu.
* show_section_headers: bool show headers before menu sections.
*
* @return string
* @since 1.8.0
