Routing
-------
A simple flood routing protocol is currently used. Every node forwards all messages, unless a message with the same Origin and Sequence Number has already been received.
Nodes MUST store pairs of (Origin, Sequence Number) for all received messages. After receiving a new message, entries with the same Origin and Sequence Number between _received_ + 1 and _received_ + 32767 MUST be removed (with a wrap around at the maximum value). The entries MUST NOT be cleared while the program is running. They MAY be cleared when the program is exited.
There is currently no support for offline messages. If sender and receiver are not in the same mesh, the message will not arrive.
Nodes are free implement different routing algorithms.
