Title: Create collection if none passed to CollectionView

Lots of logic depends on a collection existing in CollectionView and will crash if none specified. While I agree the best practice is to pass in a collection, it may be more convenient not to create one ahead of creating the view.

As this is a bit more controversial, I understand if you want to discuss it more or decline the request.
