/**
This is a refactoring of the original menu_popup.js script to use jQuery
(www.jquery.com). The original version descended the DOM looking for the
ULs containing menus based on their class then descended them and attched
closures to the LIs that contained submenus. The current version uses
jQuery selectors and events and is written as a plugin.

TO USE:

Load the jquery.menu_popup.js library after the jQuery library.
Select the menus in your document ready function and call the popupMenus()
function on them.
