Arduino PID Library

How about adding autotune capablity?

sadly, that's one thing I can't do. part of my employment agreement explicitly states that I can't tune loops (or write code that does same) except under the umbrella of my company. somehow writing an entire pid controller and making it freely available is ok though. go figure.

the library is such that someone could write a parallel program to perform autotune manipulations and get some numbers. if anyone decides to take this on (and I don't think it looks violently dangerous) I'd be happy to include it.
