Using The Firebase Backend-As-A-Service (BaaS) In AngularJS

Over the last couple of days, I've started to dig into Firebase, a data storage and data synchronization Backend-as-a-Service (Baas). Like Pusher and PubNub, it can push events over WebSockets. But, it doesn't [necessarily] deal with arbitrary events; rather, it deals with synchronization events that automatically keep local client caches in-sync with the backend data collections.
