This package lifts a mapping from coefficient rings R to S to a mapping from UnivariatePolynomial(x, R) to UnivariatePolynomial(y, S). Note that the mapping is assumed to send zero to zero, since it will only be applied to the non-zero coefficients of the polynomial.

map: (R -> S, UnivariatePolynomial(x, R)) -> UnivariatePolynomial(y, S)
map(func, poly) creates a new polynomial by applying func to every non-zero coefficient of the polynomial poly.
