title: How to get store name of Ember Data model
body: <p>How can I determine the "store name" (not sure what the proper terminology is) for a given ED Model? Say I have <code>App.Payment</code>, is there a store method that let's me look up its corresponding name, i.e. <code>payment</code> (for example to use in <code>find</code> queries)? </p>
