 * Each menu MUST have a class 'menu' set.  If the menu doesn't have this, the
 * JS won't make it dynamic.  If you want a panel to be expanded at page load,
 * give the containing LI element the classname 'expand'.  Use this to set the
 * right state in your page (generation) code.
 * Optional extra classnames for the UL element that holds an accordion:
 *		noaccordion: no accordion functionality
 *		collapsible: menu works like an accordion but can be fully collapsed
