8 * @param Function comparator:
9 *   Exactly the same behaviour as [1,2,3].sort(comparator)
10 *
11 * @param Function getSortable
12 *   A function that should return the element that is
13 *   to be sorted. The comparator will run on the
14 *   current collection, but you may want the actual
15 *   resulting sort to occur on a parent or another
16 *   associated element.
17 *
18 *   E.g. $('td').sortElements(comparator, function(){
19 *      return this.parentNode;
20 *   })
21 *
22 *   The <td>'s parent (<tr>) will be sorted instead
23 *   of the <td> itself.
