New Wiki page on the IOIO Motor Control API

[Ytai Ben-Tsvi]

Just finished a long write-up on the motor control library. Hope people will find this work useful:

While documenting, found a very minor issue with how manual mode works. I'll push a v5.01 IOIOLib soon with a fix.

Now I can go to sleep :)
