/**
 * 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 Model name can be given (see 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.
