Finite State Machine (FSM)

Example:

import FSM from './utils/fsm';

var fsm = FSM().
    addState({name: 'first', events: {next: 'second'}}).
    addState({name: 'second', events: {next: 'third', previous: 'first'}}).
    addState({name: 'third', events: {previous: 'second'}});

fsm.getState();
// -> 'first'

fsm.consume('next').getState();
// -> 'second'

fsm.consume('next').getState();
// -> 'third'

fsm.consume('next').getState();
// -> 'third', since third has no next event
