Convert y2014 to y2016, and get the drivetrain running.

I made a y2016 folder based on what was in y2014. Right now, it only has
a drivetrain control loop, and all the constants are not up to date with
the current CAD design. Changes from y2014 can be viewed by comparing to
the BASE commit, since I put this commit on top of a dummy y2014 folder
renamed y2016. Hope this helps.
