//** Featured Content destaqueGrande 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?mydestaqueGrande=4 to select 4th slide in "mydestaqueGrande")

//2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads.
