NotificationCenter

[mfclarke-ts]

Hey folks,

Not sure how we have gotten this far without it in our app, but just today we've hit the need for NotificationCenter. Looking at the recent changes to the case studies, it looks like it's recommended to use NotificationCenter wholesale in the environment without a wrapper client.

But it occurred to me that this means any unexpected usage of it in tests wouldn't be caught (ie, with a .failing version). IMHO this is a pretty significant side effect that we want to have coverage on exact usage of. Could be missing something though.... Any thoughts?

Thanks
