 // A class to implement the functionality of a host process.
 //
 // Here's the work flow of this class:
 // 1. We should load the saved GAIA ID token or if this is the first
 //    time the host process runs we should prompt user for the
 //    credential. We will use this token or credentials to authenicate
 //    and register the host.
 //
 // 2. We listen for incoming connection using libjingle. We will create
 //    a ConnectionToClient object that wraps around linjingle for transport.
