***********************************************/

//** Featured Content Slider script- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 2nd, 08'- Script rewritten and updated to 2.0.
//** June 12th, 08'- Script updated to v 2.3, which adds the following features:
			//1) Changed behavior of script to actually collapse the previous content when the active one is shown, instead of just tucking it underneath the later.
			//2) Added setting to reveal a content either via "click" or "mouseover" of pagination links (default is former).
			//3) Added public function for jumping to a particular slide within a Featured Content instance using an arbitrary link, for example.

//** July 11th, 08'- Script updated to v 2.4:
			//1) Added ability to select a particular slide when the page first loads using a URL parameter (ie: mypage.htm?myslider=4 to select 4th slide in "myslider")
			//2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads.
