Writing a book consumes much of your focus and time, and without the proper support can become difficult. Fortunately, I enjoy plenty of support in the form of Chris, Bev, and Andrew (my family), my girlfriend Elizabeth, and the people and businesses I work with, who always understand when I have to disappear for days at a time to work on "those books".

It is necessary to also thank my publishers and everyone on the Packt team for providing the resources required to get this book to print.

Finally, I want to thank my readers for allowing me to do something I enjoy. I hope that you will find plenty of value both in the book and in the accompanying exercises.
