same time (output connected to input).
The behaviour of the controller can now be described this way:
The luacontroller sets port A, then B, then C, then D; if it is
interrupted by another event during that time it stops and let the
second event do the job.
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.
