Comment:
I think there are still some problems with this. For example:
1. Pickling does not work for these objects -- one needs to define a
proper !__reduce!__ method.
2. I don't think we should continue the use of !__ attributes as they just
cause problems. For example, the code in here has to set attributes like
_PowerSeriesRing_generic!__power_series_class in subclasses.
3. There are formating issues in some of the docstrings like '_latex_'
4. We shouldn't have a 'MPowerSeriesRing' -- that functionality should
just be in PowerSeriesRing. MPolynomialRing was deprecated for the same
reason a long time ago.
