\ccDefinition

This \ccc{AdaptableUnaryFunction} computes the content of a 
\ccc{PolynomialTraits_d::Polynomial_d} with respect to the symmetric 
view on the polynomial, that is, it computes the gcd of all innermost coefficients. 

This functor is well defined if \ccc{PolynomialTraits_d::Innermost_coefficient_type} is a 
\ccc{Field} or a \ccc{UniqueFactorizationDomain}.
