/**
 * Handles the resizing of a menu according to the available screen width
 *
 * Uses themes/original/css/resizable-menu.css.php
 *
 * To initialize:
 * $('#myMenu').menuResizer(function () {
 *     // This function will be called to find out how much
 *     // available horizontal space there is for the menu
 *     return $('body').width() - 5; // Some extra margin for good measure
 * });
 *
 * To trigger a resize operation:
 * $('#myMenu').menuResizer('resize'); // Bind this to $(window).resize()
 *
 * To restore the menu to a state like before it was initialized:
 * $('#myMenu').menuResizer('destroy');
 *
