Optimizer function abstract base class.
This class provides an abstract interface for the function that is used by the GOptimizer optimization class.
The eval() method returns the function value at a given set of parameters that is defined by an instance of the optimizer parameter container class GOptimizerPars. The value() method returns the actual function value at these parameters, and the gradient() and covar() methods return pointers on the gradient vector and the covariance matrix at the parameter values.
