chg: name changes to be mathematically correct

some names were not mathematically correct but were like that just
because I copied them from gfanlib one to one.
however since I plan on developing a convex package that is a mixture
between gfanlib and polymake, and since the polymake names were chosen
with more mathematical care, I decided to make a few namechanges.
also this was an issue which has come up in previous singular meetings
fix: compiler warnings

fixed compiler warnings due to different order of initializations in constructor
(compared to how they are listed in the class).
fix: compiler warnings

fixing compiler warnings that would appear should the code be compiled
with some harder setting (which happen once autoconf is used)
