     * @class Ext.tree.TreePanel
     * @extends Ext.Panel
     * The TreePanel provides tree-structured UI representation of tree-structured data.
     * {@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.
     * A TreePanel must have a {@link #root} node before it is rendered. This may either be
     * specified using the {@link #root} config option, or using the {@link #setRootNode} method.
     * An example of tree rendered to an existing div:
    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();
     *
     * The example above would work with a data packet similar to this:
    [{
        "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"
    }]
     *
     * An example of tree within a Viewport:
    new Ext.Viewport({
        layout: 'border',
        items: [{
            region: 'west',

                }, {
                    text: 'Menu Option 2',
                    leaf: true
                }, {
                    text: 'Menu Option 3',
                    leaf: true
                }]
