Title: Pab/library fixes

.. multivaiate polynomials added.

This should be most of the remaining algebra files that were not built.
The main motivation for doing these was that #87 requires much stronger
conditional checking, and the existing library is a little lax on that front. So,
completing the library before a bunch of random conditionalisation changes seems a
good idea.

One minor issue - there's a combine function missing in action - referenced
by the multivariate gcd implementation, but not defined anywhere. I've stubbed
it in the hope that an implementation will show up.
