+ * jQuery.fn.sortElements
+ * --------------
+ * @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.
