Detailed Description

These functors take a single feature value, and return a corresponding score (and optionally also the first derivative).

Implementers should implement two functions:

• virtual double evaluate(double feature) const
• virtual DerivativePair evaluate_with_derivative(double feature) const also add IMP_OBJECT_METHODS(Name) macro for Object methods
