// Abstract interface for evaluating a real-valued function of one real variable
// and performing numerical algorithms on it. The purpose of this interface is
// to decouple RooAbsArg-specific implementations from numerical algorithms that
// only need a simple function evaluation interface. The domain of the function
// is assumed to be an n-dimensional box with edge coordinates specified by the
// the getMinLimit() and getMaxLimit() methods.
