Acknowledgements

I would like to thank my mom and dad, Gabriella and János. Without your constant love and support this book would not be possible.

I also want to thank my wife Lisa Jennifer Gordon who not only managed to put up with me through the process of writing this book, but helped create many of the illustrations in the book as well.

Finally, I want to thank my brother Martin, without his curiosity for programming the first draft of this book would not have been written.
