4.4 comms

Synposis

The comms proxy provides an interface to the network broadcast device. This device broadcasts any message sent to it onto the local network, and returns the messages broadcast by other robots. This device use broadcast UDP sockets, and therefore offers no guarantee that messages will be delivered, or that they will be delivered in the order in which they are transmitted.
