Arduino library for implementing a finite state machine.
on_state() handler to statesrun_machine() method to invoke machine execution (includes a
check_timed_transitions() call)timed_switchoff.ino example sketch to ilustrate new on_state()
and run_machine() funcionalitymake_transition() correctly initialices timed transitions start
milliseconds (make_transition() is now a fsm method)on_enter() handler is now correctly executed on fsm
