def next
  # this may rely on events having exactly one transition... otherwise, we may need an argument? (TBD) 
  next_events = aasm.events(permitted: true).map(&:name)
  __debug("choosing first from next events: #{next_events.inspect}")
  next_event = next_events.first
  __process(next_event)
  self.send(next_event)
end

#start ⇒ Object

SC also has a special action called “start” which clears state and reloads it (defaulting back to the initial state)
