Comments:
Issues with "abstract class": make sure all functions are in .h file & have some sort of implementation even if empty
For now, comment all functions dealing with reading data, return empty/default values. actuators don't get/send sensor readings
Later may return if actuator ran or not

This was finished and compiles now but has yet to be implemented into the data logger loop.

There's currently not a way to skip a given loop but we can probably do without that for now.

Driver system works. @emersonae please upload a draft PR and assign it to me, and place it in this project board.
