//   This code is part of a preliminary release of COOOL (CWP
// Object-Oriented Optimization Library) and associated class 
// libraries. 
//
// The COOOL library is a free software. You can do anything you want
// with it including make a fortune.  However, neither the authors,
// the Center for Wave Phenomena, nor anyone else you can think of
// makes any guarantees about anything in this package or any aspect
// of its functionality.
//
// Since you've got the source code you can also modify the
// library to suit your own purposes. We would appreciate it 
// if the headers that identify the authors are kept in the 
// source code.
