//** Script Download/ instructions page: http://www.dynamicdrive.com/dynamicindex1/dropmenuindex.htm
//** January 29th, 2009: Script Creation date

//**May 22nd, 09': v2.1
	//1) Automatically adds a "selectedanchor" CSS class to the currrently selected anchor link
	//2) For image anchor links, the custom HTML attributes "data-image" and "data-overimage" can be inserted to set the anchor's default and over images.

//**June 1st, 09': v2.2
	//1) Script now runs automatically after DOM has loaded. anylinkmenu.init) can now be called in the HEAD section

//Featured Content Glider: By http://www.dynamicdrive.com
//Created: Dec 22nd, 07'
//Updated (Jan 29th, 08): Added four possible slide directions: "updown", "downup", "leftright", or "rightleft"
//Updated (Feb 1st, 08): Changed glide behavior to reverse direction when previous button is clicked
//Updated (Feb 12th, 08): Added ability to retrieve gliding contents from an external file using Ajax ("remotecontent" variable added to configuration)
//Updated (July 21st, 09): Updated to work in jQuery 1.3.x
