Acknowledgments
I don't think it is possible for a person, at least, a person with a family, to write a book without a good deal of support. In my case I have had massive support from my wife, Angela who has also been a constant source of inspiration and indeed practical help by proof-reading the book. I dedicate this book to her.
I thank my extended family accrued from two marriages, that is, Callum, Rory, Connor, Edward, Tamsyn and Sophie for bringing inspiration and joy to my life as well as the inevitable problems. I would also like to thank my first wife Nerissa for supporting me in my early career and shouldering a large part of the burden of looking after our children.
Finally I would like to thank my parents who with meager resources supported me in pursuit of higher education despite their feeling that I should get a proper job.
