+ * @class Roo.tree.TreeLoader
+ * @extends Roo.util.Observable
+ * A TreeLoader provides for lazy loading of an {@link Roo.tree.TreeNode}'s child
+ * nodes from a specified URL. The response must be a javascript Array definition
+ * who's elements are node definition objects. eg:
+ * &lt;pre&gt;&lt;code&gt;
+{  success : true,
+   data :      [
+   
+    { 'id': 1, 'text': 'A folder Node', 'leaf': false },
+    { 'id': 2, 'text': 'A leaf Node', 'leaf': true }
+    ]
+}
+
+
+&lt;/code&gt;&lt;/pre&gt;
+ * &lt;br&gt;&lt;br&gt;
+ * The old style respose with just an array is still supported, but not recommended.
+ * &lt;br&gt;&lt;br&gt;
+ *
+ * A server request is sent, and child nodes are loaded only when a node is expanded.
+ * The loading node's id is passed to the server under the parameter name &quot;node&quot; to
+ * enable the server to produce the correct child nodes.
+ * &lt;br&gt;&lt;br&gt;
+ * To pass extra parameters, an event handler may be attached to the &quot;beforeload&quot;
+ * event, and the parameters specified in the TreeLoader's baseParams property:
+ * &lt;pre&gt;&lt;code&gt;
+    myTreeLoader.on(&quot;beforeload&quot;, function(treeLoader, node) {
+        this.baseParams.category = node.attributes.category;
+    }, this);
+&lt;/code&gt;&lt;/pre&gt;&lt;
+ * This would pass an HTTP parameter called &quot;category&quot; to the server containing
+ * the value of the Node's &quot;category&quot; attribute.
+ * @constructor
+ * Creates a new Treeloader.
+ * @param {Object} config A config object containing config properties.
