I went through the Abelian groups and ported them over to the new Parent.
Together with some cleanups to whatever I came across in the process. This
is in

Since it is a pretty big patch I would appreciate if somebody could review
it before conflicting stuff start

I think that, at some point, the framework should be aware of the
internal operations in the corresponding parent. I mean: if we are
talking about algebras, the expression of an element in terms of the
generators will include products, sums, and multiplication by scalars.
If we are talking about a

can define a morphism just by passing a list with the images of the
generators to .hom() But apparentñy, it has to be done by hand for
each case. Would it be pos

Yes, all have.
That's to say, sage.structure.parent.Parent provides the infrastructure for
generators.
