*
* Contains a collection of all stores that are created that have an identifier. An identifier can be assigned by
* setting the {@link Ext.data.AbstractStore#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'
* });
*
* Ext.create('Ext.view.View', {
* store: 'myStore',
* // other configuration here
* });
