have you considered extending this to all RealmCollection types?

RealmResultsController displays a list of filtered objects based on type.

I was wondering if you've looked into creating a way to do this for all RealmCollection types, though. Anything that's a RealmCollection implements addNotificationBlock. If RealmResultsController could take an init that could pass in a RealmCollection, that would be pretty cool. Then it could handle List and LinkingObjects, too.
