/*
This service manages shared state between *instances* of recent lists. The
recents controller will hook into this central service to get things like:
- which rooms should be highlighted
- which rooms have been binged
- which room is currently selected
- etc.
This is preferable to polluting the $rootScope with recents specific info, and
makes the dependency on this shared state *explicit*.
