 * This creates a state machine. The state machine is a Mealy machine but outputs are generated
 * independent of the state transition. As you can see in the arguments, the "action" function
 * (which generates outputs) is distinct from the "next" function, which calculates the next state.
 * The implementation of "action" is of course left to you though, so you can totally just ignore
 * the current value and make this a Moore machine.
