B4R Library rFastPID

A wrap for this Github project. Not sure I have it 100% correct - maybe someone has use for it and can amend it. Have tested it with "mixed" results.

It is the "completed" library for this post as the code in the below post does not include the completed library:

I think this one works better - far more stable:

The FastPID library in post #1 of this thread seems to be a bit unstable even when using it with inline C. Seems to oscillate too much around the set point regardless of changing the Kp, Ki, and Kd parameters.
