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

        // proxy configs
        url: 'get-images.php',

        // reader configs
        root: 'images',
        idProperty: 'name',
        fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
    });
     * </code></pre></p>
     * <p>This store is configured to consume a returned object of the form:<pre><code>
    stcCallback({
        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>Where stcCallback is the callback name passed in the request to the remote domain. See {@link Ext.data.proxy.JsonP JsonPProxy}
     * for details of how this works.</p>
     * An object literal of this form could also be used as the {@link #data} config option.</p>
     * <p><b>*Note:</b> Although not listed here, this class accepts all of the configuration options of
     * <b>{@link Ext.data.reader.Json JsonReader}</b> and <b>{@link Ext.data.proxy.JsonP JsonPProxy}</b>.</p>
     * @xtype jsonpstore
