Version 2.2.0 released

[chmarti1]

It has been a long time coming, and many of you have been patient as we have worked to release PYroMat version 2.2.0. This is the first in a long series of exciting updates to PYroMat that we are planning for the coming years.

In this release, you'll find an even more flexible property interface that does away with "inverse" property algorithms. Now, we just "figure it out" in the background. If you have enthalpy and pressure and you want temperature, that's what you type.

>>> import pyromat as pm
>>> h2o = pm.get('mp.H2O')
>>> h2o.T(h=1200,p=3.2)
array([408.88731894])

All the old inverse methods (like T_h) are still there for reverse compatibility.

Plus, we've added more multi-phase support. Now, you can find R-1234ze and cryogenic oxygen. There are more on the way, like R-1234yf, argon, hydrogen, and others.

If you use T_h() or T_s() with positional arguments (e.g. T_h(hvalue, pvalue) instead of T_h(h=hvalue, p=pvalue) version 2.2.0 may have given you some unexpected behaviors (see Issue #52). To preserve reverse compatibility, inverse routines are just wrapper functions, so calling T_h() is really a call to T(), but the new wrapper methods had slightly different call signatures, so if you aren't passing values by keyword, you might see unexpected changes in behavior. Version 2.2.2 fixes this issue by forcing the new call signatures to match the original methods.
