It's hard to understand how much effort is involved in writing a book until you've done it. Completion of this book would have been impossible without the support of my family. I would like to thank Katarina, my wife, partner, and friend, for all her encouragement. I also want to thank my children, Thomas and Maria, for inspiring me.

Additionally, I would also like to thank Packt Publishing for giving me the opportunity to write this book, and for their support and guidance in the difficult task of writing this book.
