     * Contains a collection of all stores that are created that have an identifier. An identifier can be assigned by
     * setting the {@link Ext.data.Store#storeId storeId} property. When a store is in the StoreManager, it can be
     * referred to via it's identifier:
     *
     *     Ext.create('Ext.data.Store', {
     *         model: 'SomeModel',
     *         storeId: 'myStore'
     *     });
     *
     *     var store = Ext.data.StoreManager.lookup('myStore');
     *
     * Also note that the {@link #lookup} method is aliased to {@link Ext#getStore} for convenience.
     *
     * If a store is registered with the StoreManager, you can also refer to the store by it's identifier when registering
     * it with any Component that consumes data from a store:
     *
     *     Ext.create('Ext.data.Store', {
     *         model: 'SomeModel',
     *         storeId: 'myStore'

     *         store: 'myStore',
