Polynomial.py - A set of utilities to manipulate polynomials. This consists
of a set of simple functions to convert polynomials to a Python list, and
manipulate the resulting lists for multiplication, addition, and
power functions. There is also a class that wraps these functions
to make their use a little more natural.
This can also evaluate the polynomials at a value, and take integrals
and derivatives of the polynomials.
