Implement interrupt(time, iid): The whole code is called again after a
certain amount of time. Whenever it is called, an event is set. Possible events are: program, interrupt, on and off It also contains additional information (on/off -> event.in; interrupt -> event.iid) iid must be an integer or string value, otherwise the interrupt is not active
