Comment:
Finally I have posted a combined patch that also includes the recent ideas
on _meet_, adds several doctests and fixes some of the missing calls to
`__init__` of base classes I was mentioning.
It also comprises Nicolas' review patch, with the only exception that I am
now not using a separate function for computing the category of a homset.
If I see that correctly, all new stuff is backed up by doc tests. I did a
complete test ''without'' using the review patch. I'm testing the latest
patch version now, but I think it is "needs review"!
I think Nicolas is an author as well: He provided the original
implementation of Category_singleton.
