I'm sure this is very useful, but I have to say once again that
"Poly_Mapping" is probably not a good name for this now that it is
disconnected from its original application of multivariate polynomials.
I vaguely recall that we had this discussion already a while ago and
didn't really resolve it.
I currently don't have any input beyond that (I'm feeling a bit poorly);
I just wanted to point this out.

I am gradually installing the components of this development in various places, and think that Poly_Mapping could go into Library, as it depends only on other Library entries. I hope nobody objects to this. Then I guess the duplicate in the AFP should be deleted.
