DESCRIPTION
    DirectObjectiveFunction
     This is a class of customerized objective function
     passes through SlaveForward. When the user-written
     objective-function evaluation code is used for the
     optimization, this class should be used for passing 
     values to the optimizer.
     See also SlaveForward, ObjFcn.
    
     Both value and derivatives can be passed through this 
     class. You can choose either providing your own derivative
     evaluation or using the finite-difference scheme provided 
     by COOOL.
