/**
 * @class Ext.tree.TreePanel
 * @extends Ext.Panel
 * <p>The TreePanel provides tree-structured UI representation of tree-structured data.</p>
 * <p>{@link Ext.tree.TreeNode TreeNode}s added to the TreePanel may each contain metadata
 * used by your application in their {@link Ext.tree.TreeNode#attributes attributes} property.</p>
 * <p><b>A TreePanel must have a {@link #root} node before it is rendered.</b> This may either be
 * specified using the {@link #root} config option, or using the {@link #setRootNode} method.
 * <p>An example of tree rendered to an existing div:</p><pre><code>
var tree = new Ext.tree.TreePanel({
    renderTo: 'tree-div',
    useArrows: true,
    autoScroll: true,
    animate: true,
    enableDD: true,
    containerScroll: true,
    border: false,
    // auto create TreeLoader
    dataUrl: 'get-nodes.php',

    root: {
        nodeType: 'async',
        text: 'Ext JS',
        draggable: false,
        id: 'source'
    }
});

tree.getRootNode().expand();
 * </code></pre>
 * <p>The example above would work with a data packet similar to this:</p><pre><code>
[{
    "text": "adapter",
    "id": "source\/adapter",
    "cls": "folder"
}, {
    "text": "dd",
    "id": "source\/dd",
    "cls": "folder"
}, {
    "text": "debug.js",
    "id": "source\/debug.js",
    "leaf": true,
    "cls": "file"
}]
 * </code></pre>
 * <p>An example of tree within a Viewport:</p><pre><code>

    layout: 'border',
