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
It still misses some functionality such as a persistent memory and a
timer, but that is subject to change. The code runs in a sandbox.
Speaking long term this will hopefully replace the old controller.
