Once again, I have been supported by a great team. In particular, Kate Shoup has done a tremendous job of turning my prose into a proper book, with correct formatting, a nice layout, and flowing text. Thanks also to the technical reviewer, Maneesh Sethi, for making sure I made sense, technically speaking. Also, thanks must go to the collection of managing editors, layout staff, and everyone else at Cengage who’s helped me by managing the project and letting me get on with the writing.

As always, I beg forgiveness from my family for the occasional book-related rant, and the bouts of isolation as I hammered out the chapters, and thank them for sticking by me through yet another book project.
