-A TreeLoader provides for lazy loading of an <a ext:cls="Ext.tree.TreeNode" href="output/Ext.tree.TreeNode.html">Ext.tree.TreeNode</a>'s child
-nodes from a specified URL. The response must be a JavaScript Array definition
-whose elements are node definition objects. eg:
-<pre><code>[{
- id: 1,
- text: <em>'A leaf Node'</em>,
- leaf: true
- },{
- id: 2,
- text: <em>'A folder Node'</em>,
- children: [{
- id: 3,
- text: <em>'A child Node'</em>,
- leaf: true
- }]
- }]</code></pre>
-<br><br>
-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 "node" to
-enable the server to produce the correct child nodes.
-<br><br>
-To pass extra parameters, an event handler may be attached to the "beforeload"
-event, and the parameters specified in the TreeLoader's baseParams property:
-<pre><code>myTreeLoader.on(<em>"beforeload"</em>, <b>function</b>(treeLoader, node) {
- <b>this</b>.baseParams.category = node.attributes.category;
- }, <b>this</b>);</code></pre>
-This would pass an HTTP parameter called "category" to the server containing
-the value of the Node's "category" attribute. </div>

-<b>Combining Options</b><br>
-Using the options argument, it is possible to combine different types of listeners:<br>
-<br>
-A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
-<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, {
- single: true,
- delay: 100,
- forumId: 4
-});</code></pre>
-<p>
-<b>Attaching multiple handlers in 1 call</b><br>
-The method also allows for a single argument to be passed which is a config object containing properties
-which specify multiple handlers.
-<p>
-<pre><code>foo.on({
- <em>'click'</em> : {
- fn: <b>this</b>.onClick,
- scope: <b>this</b>,
- delay: 100
- },
- <em>'mouseover'</em> : {
- fn: <b>this</b>.onMouseOver,

- <em>'mouseout'</em> : {
