/* 
Simple JQuery menu.
Copyright 2008 by Marco van Hylckama Vlieg

Notes: 

1: each menu MUST have an ID set. It doesn't matter what this ID is as long as it's there.
2: each menu MUST have a class 'menu' set. If the menu doesn't have this, the JS won't make it dynamic

Optional extra classnames:

noaccordion : no accordion functionality
collapsible : menu works like an accordion but can be fully collapsed
expandfirst : first menu item expanded at page load
