Detailed Description

A subclass of EvaluationContext to be used with ConcreteFunctionals.

Since a ConcreteFunctional does not use an EvaluationContext to save its state, an instance of ConcreteEvaluationContext simply sends the current point to a ConcreteFunctional, and lets the ConcreteFunctional perform the evaluation. The method values() is specialized to call the concreteValues() method of a ConcreteFunctional. A similar arrangement holds for grads() and hessian().
