//** Simple Controls Gallery- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com
//** Dec 7th, 08'- Script created (Requires jquery 1.2.x)
//** February 6th, 09'- Updated to v 1.3:
	//1) Adds Description Panel to optionally show a textual description for each slide
	//2) In Auto Play mode, you can now set the number of cycles before gallery stops.
	//3) Inside oninit() and onslide(), keyword "this" now references the current gallery instance
