   * 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}.
   *
   * A store configuration would be something like:
   *
   *     var store = new Ext.data.JsonStore({
   *         // store configs
   *         storeId: 'myStore',
   *
   *         proxy: {
   *             type: 'ajax',
   *             url: 'get-images.php',
   *             reader: {
   *                 type: 'json',
   *                 rootProperty: 'images'
   *             }
   *         },
   *
   *         //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'}]
   *     });
   *
   * This store is configured to consume a returned object of the form:
   *
   *     {
   *         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)}
   *         ]
   *     }
   *
   * An object literal of this form could also be used as the {@link #cfg-data} config option.
   *
