</span> * @author Ed Spencer
 *
 * &lt;p&gt;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}.&lt;/p&gt;
 *
 * &lt;p&gt;A store configuration would be something like:&lt;/p&gt;
 *
&lt;pre&gt;&lt;code&gt;
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'}]
});
&lt;/code&gt;&lt;/pre&gt;
 *
 * &lt;p&gt;This store is configured to consume a returned object of the form:&lt;pre&gt;&lt;code&gt;
{
    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)}
    ]
}
&lt;/code&gt;&lt;/pre&gt;
 *
 * &lt;p&gt;An object literal of this form could also be used as the {@link #cfg-data} config option.&lt;/p&gt;
