## Supervision Tree

The highlighted processes below (supervisor and servers) are fault-tolerant:
if any crashes (or is killed), it is immediately restarted and the system
remains undisturbed.

The processes identified by their PIDs are game servers: each holds a game
struct as its state. Multiple games can be played simultaneously.
