    /**
     * @class Ext.data.ArrayStore
     * @extends Ext.data.Store
     * Formerly known as "SimpleStore".
     * Small helper class to make creating {@link Ext.data.Store}s from Array data easier.
     * An ArrayStore will be automatically configured with a {@link Ext.data.ArrayReader}.
     * A store configuration would be something like:
    var store = new Ext.data.ArrayStore({
        // store configs
        autoDestroy: true,
        storeId: 'myStore',
        // reader configs
        idIndex: 0,
        fields: [
           'company',
           {name: 'price', type: 'float'},
           {name: 'change', type: 'float'},
           {name: 'pctChange', type: 'float'},
           {name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
        ]
    });
     *
     * This store is configured to consume a returned object of the form:
    var myData = [
        ['3m Co',71.72,0.02,0.03,'9/1 12:00am'],
        ['Alcoa Inc',29.01,0.42,1.47,'9/1 12:00am'],
        ['Boeing Co.',75.43,0.53,0.71,'9/1 12:00am'],
        ['Hewlett-Packard Co.',36.53,-0.03,-0.08,'9/1 12:00am'],
        ['Wal-Mart Stores, Inc.',45.45,0.73,1.63,'9/1 12:00am']
    ];
     *
     * An object literal of this form could also be used as the {@link #data} config option.
     * *Note: Although not listed here, this class accepts all of the configuration options of
     * {@link Ext.data.ArrayReader ArrayReader}.
     * @constructor
     * @param {Object} config
     * @xtype arraystore
