     * <p>Small helper class to make creating {@link Ext.data.Store}s from JSON data easier.
     * A JsonStore will be automatically configured with a {@link Ext.data.reader.Json}.</p>
     *
     * <p>A store configuration would be something like:</p>
     *
    <pre><code>
    var store = new Ext.data.JsonStore({
        // store configs
        storeId: 'myStore',

        proxy: {
            type: 'ajax',
            url: 'get-images.php',
            reader: {
                type: 'json',
                root: 'images',
                idProperty: 'name'
            }
        },

        //alternatively, a {@link Ext.data.Model} name can be given (see {@link Ext.data.Store} for an example)
        fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
    });
    </code></pre>
     *
     * <p>This store is configured to consume a returned object of the form:<pre><code>
    {
        images: [
            {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},
            {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)}
        ]
    }
    </code></pre>
     *
     * <p>An object literal of this form could also be used as the {@link #cfg-data} config option.</p>
