Comment(by SimonKing):
Currently I work on the following technical problem:
The category of a quotient ring is not properly initialised. Thus, a
proper `TestSuite` is not available. I guess, a quotient ring of a ring R
should belong to the category `R.category().Quotients()`. Doing, so, there
are further problems, since some crucial methods such as `lift` have a
completely different meaning in sage.rings.quotient_rings and
sage.categories.quotients.
So, that mess needs to be cleaned up.
