/**
 * @class Ext.data.JsonStore
 * @extends Ext.data.Store
 * <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.JsonReader}.</p>
 * <p>A store configuration would be something like:<pre><code>
var store = new Ext.data.JsonStore({
    // store configs
    autoDestroy: true,
    url: 'get-images.php',
    storeId: 'myStore',
    // 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>
{
    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>
 * 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.JsonReader JsonReader}</b>.</p>
 * @constructor
 * @param {Object} config
 * @xtype jsonstore
