 * @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>
 *    <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 $('#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});
 * 
 * @param String titleOpacity
 *          the opacity of your title bar (if present)
 * 
 * @example $('#gallery').jqGalScroll({titleOpacity:.70});
 * 
 * @param String direction 
 *          vertical horizontal diagonal
 * 
 * @example $('#gallery').jqGalScroll({direction:'vertical'});
 *
