ABSTRACT
ACKNOWLEDGEMENTS Producing a book is a long, and at times tortuous, process that relies on the good will and contribution of a lot of people to make happen. As the author, I’d like to thank the people at Focal Press, the publisher of this book, to start with. Katy Spencer for commissioning the project in the first place, Dave Bevans for getting things underway and especially Lauren Mattos for guiding the project along from the very beginning with a steady hand.
