+    params: { .... },
+    success : function(res) {
+        Roo.log(res.data);
+        Roo.log(res.total);
+        ....
+    } 
+});
+
+</code></pre>
+* 
+* @constructor
+* @param {Object} cfg   Configuration object.
+* @cfg {String} url     Location to download from.
+* @cfg {String} method     GET or POST (default GET), POST will create a form, and post that into the hidden frame.
+* @cfg  {Object/String/Function} params (Optional) An object containing properties which are used as parameters to the
