+/**
+ * When sorting html links in a DataTable column you might 
+ * want to sort it by link text not url.
+ * 
+ * For example "asc" by text not html link code:
+ * 
+ * <a href="http://3example.com">1 Link text</a>
+ * <a href="http://2example.com">2 Link text</a>
+ * <a href="http://1example.com">3 Link text</a>
+ * 
+ * @name linktext.js
+ * @summary Sort link text not url.
+ * @author Darek L https://github.com/dprojects
+ * 
+ * @example
+ * 
+ *      gTable = $('#demo-table').DataTable({
+ *                  "orderClasses": true,
+ *                  "responsive": true,
+ *                  "columnDefs": [ { "type": "linktext", "targets": 1 } ],
+ *                  "order": [1, "asc"]
+ *      });
+ * 
+ * To change order later:
+ * 
+ *      gTable.order([1, 'desc']).draw();
