//Step Carousel Viewer: By Dynamic Drive, at http://www.dynamicdrive.com
//** Created: March 19th, 08'
//** Aug 16th, 08'- Updated to v 1.4:
	//1) Adds ability to set speed/duration of panel animation (in milliseconds)
	//2) Adds persistence support, so the last viewed panel is recalled when viewer returns within same browser session
	//3) Adds ability to specify whether panels should stop at the very last and first panel, or wrap around and start all over again
	//4) Adds option to specify two navigational image links positioned to the left and right of the Carousel Viewer to move the panels back and forth

//** Aug 27th, 08'- Nav buttons (if enabled) also repositions themselves now if window is resized

//** Sept 23rd, 08'- Updated to v 1.6:
	//1) Carousel now stops at the very last visible panel, instead of the last panel itself. In other words, no more white space at the end.
	//2) Adds ability for Carousel to auto rotate dictated by the new parameter: autostep: {enable:true, moveby:1, pause:3000}
	//2i) During Auto Rotate, Carousel pauses onMouseover, resumes onMouseout. Clicking Carousel halts auto rotate.

//** Oct 22nd, 08'- Updated to v 1.6.1, which fixes functions stepBy() and stepTo() not stopping auto stepping of Carousel when called.
//** July 10th, 09'- Updated to v 1.6.2- Adds jQuery.noconflict to work better with other libraries
