+ * post-menu.js - adds dropdown menu to posts
+ *
+ * Creates a global Menu object with four public methods:
+ *
+ *   Menu.onclick(fnc)
+ *     registers a function to be executed after button click, before the menu is displayed
+ *   Menu.add_item(id, text[, title])
+ *     adds an item to the top level of menu
+ *   Menu.add_submenu(id, text)
+ *     creates and returns a List object through which to manipulate the content of the submenu
+ *   Menu.get_submenu(id)
+ *     returns the submenu with the specified id from the top level menu
+ *
+ *   The List object contains all the methods from Menu except onclick()
+ *
+ *   Example usage:
+ *     Menu.add_item('filter-menu-hide', 'Hide post');
+ *     Menu.add_item('filter-menu-unhide', 'Unhide post');
+ *
+ *     submenu = Menu.add_submenu('filter-menu-add', 'Add filter');
+ *         submenu.add_item('filter-add-post-plus', 'Post +', 'Hide post and all replies');
+ *         submenu.add_item('filter-add-id', 'ID');
+ *  
+ * Usage:
+ *   $config['additional_javascript'][] = 'js/jquery.min.js';
+ *   $config['additional_javascript'][] = 'js/post-menu.js';
