Allowing independent sections of code to communicate with each other through channels without needing to import each other's code.

• Code should only have to import the pubsub module

• local channel: this is a wrapper for golang channels
• remote channel (tcp): this is a tcp/ip wrapper
• remote channel (udp): an udp wrapper

Registry:

A channel is registered to a specific path, ie "/FNode0/state/missing_messages", which is considered the base path. The factory can be retrieved via this path. Every new subscriber is assigned an internal id staring with 0 and has a dedicated path to use in logging, ie "/FNode0/state/missing_messages/0".
