   4                         //1) Changed behavior of script to actually collapse the previous content when the active one is shown, instead of just tucking it underneath the later.\r
   5                         //2) Added setting to reveal a content either via "click" or "mouseover" of pagination links (default is former).\r
   6                         //3) Added public function for jumping to a particular slide within a Featured Content instance using an arbitrary link, for example.\r
   7 \r
   8 //** July 11th, 08'- Script updated to v 2.4:\r
   9                         //1) Added ability to select a particular slide when the page first loads using a URL parameter (ie: mypage.htm?myslider=4 to select 4th slide in "myslider")\r
  10                         //2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads.\r
