Acknowledgments

I would like to thank two Michelles in my life: my wife, Dr. Michelle Smith, who has put up with many long hours devoted to my computer, and my editor, Michelle Newcomb. They have both been very patient with me while I have worked on this, my first print book. It's been a long road with a few surprises , and I've really appreciated the support. Thanks also to Chris, for many hours of diversion while I should have been concentrating .
