//Version 1.1 (March 5th, 2010): Each flex menu (UL) can now be associated with a link dynamically, and/or defined using JavaScript instead of as markup.
//Usage: $(elementselector).addpopupmenu('menuid')
//ie:
//jQuery(document).ready(function($){
//$('a.mylinks').addpopupmenu('popupmenu1') //apply popup menu with ID "popmenu1" to links with class="mylinks"
//})
