As far as putting the logic that is currently in `Brainstem.Expectation` into the loader, I wanted to try and keep as much of the expectation logic out of the loaders as possible and `#_handleCollectionResults`/`#_handleModelResults` are all expectation logic.

However, I think it would make sense if the current `#_updateStorageManagerFromResponse` method on the loaders is the one that this delegated to (since it wouldn't have to switch).

I'll chat with you in person about it, as I have a few questions.
