Comment:
The docbuild issue was from making duplicate references. You only need to
declare the references once. I fixed that and some minor formatting/doc
issues.
As for testing: The functionality is working successfully, but there are
two issues to address:
1) the `assert` statements need to be switched to `raiseerror` so that is
raises the appropriate error on failure (not just asserterror)
2) I think the speed can be greatly improved on average by changing the
way the matrix is built. Currently, all possible monomials are generated
and then each entry in the matrix is filled in by checking the coefficient
of that monomial in the polynomials. Since I would expect 'most'
polynomials to be sparse, it should be more efficient to start with a
matrix of all 0s and fill in only those entries corresponding to
appropriate monomials in the polynomials.
