* Class containg global server-side private message relay logic

* Exists to make broadcasting channel queues to groups of authenticated users with the 'read-queue' perm as painless as possible,
* reducing DB call/perm checks to just connection time, and not requireing any out-of-library user iteration at broadcast time.
*
* Calls to modify and write to the schedule are still handled by the main namespace
* This is both for it's ease of access to the rest of the channel logic, but also to keep this class as small as possible.
