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
