I would like to thank the staff at Que Publishing, in particular, Betsy Brown, who guided me throughout the progress of the work, Dayna Isley, who provided many helpful suggestions for improving the manuscript, and Tonya Simpson, who guided the manuscript through the production process. I am also indebted to Chris Crayton for his technical comments, which proved very helpful in completing this project. I would also like to thank my wife, Terry, for standing by me during the hours I had to devote to completing this work.
