+/**
+ * jQuery.fn.sortElements
+ * --------------
+ * @author James Padolsey (http://james.padolsey.com)
+ * @version 0.11
+ * @updated 18-MAR-2010
+ * --------------
+ * @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').sortElements(comparator, function(){
+ *      return this.parentNode;
+ *   })
+ *
+ *   The <td>'s parent (<tr>) will be sorted instead
+ *   of the <td> itself.
