This will restart the server after a 1s sleep, every time it either loses connection from the BCI, or else some fatal exception (fail fast).
The server internally will:
- listen on two ports (3001 for unity connections, 3000 for BCI connections)
- send "ping" strings to BCI every 5s
- forward all messages from unity onwards to BCI
- forward well-formed messages from BCI onwards to unity
Internally an event emitter called interchange is used to coordinate
the two websocket servers.
