//This jQuery plugin wraps element(s) with div tags that are used to rendered rounded corners.
//The rounded corners implementation was obtained from
//http://www.schillmania.com/projects/dialog/png/
//The following is the html structure after running this pluging against a div tag
//with id='foo'
//<div class="rounded-corners">
// <div class="rounded-corners-hd"><div class="rounded-corners-c"></div></div>
// <div class="rounded-corners-bd">
//  <div class="rounded-corners-c">
//   <div class="rounded-corners-s">
//    <div id=-'foo'>
//    </div>
//   </div>
//  </div>
// </div>
// <div class="rounded-corners-ft"><div class="rounded-corners-c"></div></div>
//</div>
