r4.3.0

Released to PyPI:

• integer variables of candidate solutions are rounded (addressing also issue
  #286)
• moved main docstring from fmin to fmin2
• experimental plots for error estimates and sensitivities
• fix numpy scalar type representations at various places
• replace ineffective use_archives flag with archive_sent_solutions
  and archive_after_sent

r4.0.0

• majorly improved mixed-integer handling based on a more concise lower bound of variances and on so-called integer centering
• moved options and parameters code into a new file
• many small-ish fixes and improvements

Smallish fixes and improvements and a constraints use case notebook.

r3.2.1

• fixes plot of principal axes which were shown squared by mistake

r3.2.0

• constraints handling via a dynamic unconstrained function instantiated from cma.ConstrainedFitnessAL.
• many small improvements and fixes

r3.1.0

• fix return value of fmin_con and make it more usable, added attribute best_feasible
• polish evolution_strategy.py
• fix a few smallish bugs

r3.0.3

Fix bug when passing args in OOOptimizer.optimize.
