 * @copyright (c) 2007 Benjamin Sterling, KenzoMedia
 * @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 $('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>

 * @example $('#gallery').jqGalScroll({speed:1000});
 
 * @param String speed
 * fast, slow, 1000, ext..
 * 
 * @example $('#gallery').jqGalScroll({speed:1000});
 * 
 * @param String height
 * the default height of your wrapper
 * 
 * @example $('#gallery').jqGalScroll({height:490});
