 * @param Function comparator:
 *   Exactly the same behaviour as [1,2,3].sort(comparator)
 *   
 * @param Function getSortable
 *   A function that should return the element that is
 *   to be sorted. The comparator will run on the
 *   current collection, but you may want the actual
 *   resulting sort to occur on a parent or another
 *   associated element.
 *   
 *   E.g. $('td').sort(comparator, function(){
 *      return this.parentNode; 
 *   })
 *   
 *   The <td>'s parent (<tr>) will be sorted instead
 *   of the <td> itself.
