Folding polynomial is unique

Polynomial.FoldingPolynomial.folding_polynomial_is_unique'

Project documentation

Alternative uniqueness theorem for the folding polynomial. The only difference is the h_x condition which in this theorem is only and inequality. Handy in practice since degreeX is defined as a supremum so inequality is much easier to prove for it.
