Create a PID tunning function

See original GitHub issue

Create a PID tunning function and also wrap it to matlab compatibility.

It must heritage the tf class as answer and print in the format Kp + Ki * 1/s + Kd * s instead num / den format.

A mildly acceptable autotuner work is a lot of work. Under the pidtune of matlab there is the same machine that also runs hinfstruct etc. in a nutshell solves a NON3 (nontrivial nonsmooth nonconvex) optimization problem. Something that comes close to it is HIFOO solver but the authors (which I knew some of them) refused to unGPL it to get it out of matlab domain. So I skipped it in the past and I need to find some time to read the article version.

Otherwise it won’t move far from returning meaningful results for bunch of 2nd order systems but fail on almost everything else.

Good point, even because this will make possible Hinf, H2 and other control calculations.

The most advanced solver that I know in Python is cvxpy (convex solver), that is not the needed here.
