Steam Piston Valve Controller

A Simple Valve Controller for the Steam Pistons.
Usage:
On the Piston, you'll need 4 on/off Valves on each port.
The outputs are referred as "Exhaust Valves", and the Upper ones are the ones near the top of the piston respectively.
Once you connect all of them up, all you need to do is have the piston move a bit (usually use a small motor that just starts moving the piston slowly, so the MC can determine what valves it should open, but you can usually just get away with an offset piston that can start turning it), then give it steam and you should be good to go!
