//** Simple Controls Gallery- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com
//** Dec 7th, 08'- Script created
//** 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
//** May 16th, 11'- Updated to v 1.4: Adds ability to show image gallery only after all images within gallery has been loaded. Requires jQuery 1.5+
//** Oct 6th, 15- Updated to v 1.5:
//1) Gallery made responsive and mobile friendly, by supporting a percentage "width" value and swipe/ touch support. Requires Touch Swipe Library
//2) Adds a new "scaleimage" option to scale the images inside the gallery in 2 different ways.
