Implement a ShareRoomsCollection, and instantiate a shareRoomsCollection in
the root ShareRoomsRootView.

Derive MyShareRoomsCollection from the new ShareRoomsCollection.

Also, trying an experiment to add "which" identifiers to prototypes, so
the type of objects is easier to identify while debugging.
Provide a way to return the remote share room, so we have the data for
presentation in the view.
