/**
 * Very simple Mealy style finite state machine relying on a nodejs event emitter. Absolutely not tested
 * and contains absolutely no fancy feature. You can put multiple "from" and "to" states by separating
 * them with a space. Putting no "from" or "to" amounts to setting them as "undefined", a supported state.
