Modified from google GCM quickstart example. See: git clone https://github.com/googlesamples/google-services.git

Intention of this app is to create a reflector message passing service using GCM such that all devices belonging to a single user (per google account id) can broadcast messages to all devices in the group through GCM.

Please refer to google documentation for the basics of GCM and for operation of the sources this project builds upon.
