 * @extendThanks Koesmanto Bong http://www.koesbong.com/
 *		Koes put a fire under my butt to improve this plugin
 *		and when I took too long he took what I had and added
 *		the horizontal scroll and in turn I ripped it from his
 *		hands and made it better :)

 *
 * @name jqGalScroll
 * @example jQuery('ul').jqGalScroll();
 * 
 * @Semantic requirements:
 * 				The structure fairly simple; the structure should consist
 * 				of a ul > li > img structure.
 * 
 * 	<ul>
 *		<li><img src="common/img/dsc_0003.thumbnail.JPG"/></li>
 *		<li><img src="common/img/dsc_0012.thumbnail.JPG"/></li>
 *	</ul>
 *
 * @param String ease
 *					refer to http://gsgd.co.uk/sandbox/jquery.easing.php for values
 * 
 * @example jQuery('#gallery').jqGalScroll({speed:1000});
 
 * @param String speed
 * 					fast, slow, 1000, ext..
 * 
 * @example jQuery('#gallery').jqGalScroll({speed:1000});
 * 
 * @param String height
 * 					the default height of your wrapper
 * 
 * @example jQuery('#gallery').jqGalScroll({height:490});
 * 
 * @param String titleOpacity
 * 					the opacity of your title bar (if present)
 * 
 * @example jQuery('#gallery').jqGalScroll({titleOpacity:.70});
 * 
 * @param String direction 
 *					vertical horizontal diagonal
 * 
 * @example jQuery('#gallery').jqGalScroll({direction:'vertical'});
