//Version 1.1 (Feb 19th, 2010): Each flex menu (UL) can now be associated with a link dynamically, and/or defined using JavaScript instead of as markup.
//Version 1.2 (July 2nd, 2011): Menu updated to work properly in popular mobile devices such as iPad/iPhone and Android tablets.
//Version 1.3 (Oct 20th, 2011): Menu fixed to be able to open the page-link of a parent on mobile devices. (ageesen@videro.com)

//Usage: $(elementselector).addflexmenu('menuid', options)
//ie:
//jQuery(document).ready(function($){
//$('a.mylinks').addflexmenu('flexmenu1') //apply flex menu with ID "flexmenu1" to links with class="mylinks"
//})
