Class used for communicating between multiple instances of Pro using a publish/subscribe model.
Messages are organized around a uniquely named channel. Subscribers can limit what messages they receive by subscribing to a
specific channel. Publishers specify a channel when posting messages. Calling publish when fewer than two instances of
Pro are running will produce no messages.
