CGAL 5.4  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.
