CGAL 5.0.1 - Polynomial

This AdaptableUnaryFunction
computes the degree of a PolynomialTraits_d::Polynomial_d
with respect to a certain variable.
The degree of p with respect to a certain variable x_i, is the highest power e of x_i such that the coefficient of x_i^{e} in p is not zero.
For instance the degree of p = x_0^2x_1^3+x_1^4 with respect to x_1 is 4.
The degree of the zero polynomial is set to 0. From the mathematical point of view this should be -infinity, but this would imply an inconvenient return type.
