[theKashey]

• contains(name, MachineDef, [states], [conditions]) to define submachines
• on('@attach') event, triggered on machine creation
• on('@detach') event, triggered on machine destruction
• .children[name] to access child machines
• contains(name) to check containtent existance.
• signalFrom(nameMachine, event, [states]) - to respont to signals.

const clockMachine = faste()
 .on('@init',({setState, attrs, trigger}) => setState({ 
    interval: setInterval(() => emit('next'), attrs.duration)
 }))
 .on('@destroy', ({state}) => clearInterval(state.interval));

const light = faste()
  // simple machine
  .contains('clock', clockMachine)
  // with dynamic constructor
  .contains('clock', ({attrs}) => ({faste: clockMachine, attrs: { duration: attrs.duration || 10}})))

  .signalFrom('clock', 'tick', ({emit}) => trigger('switch'))
