Thanks again. Must be something about my first shot at a tutorial, while at the same time trying to remember to use proper tags (<code>, etc.), while at the same time discussing a highly technical subject... my spelling digressed fifteen years. You would think I was a product of outcome based education.

Anyway, spell check is in order next time, assuming I emerge from this experience still alive and eager to do it again.

Your comments are appreciated. As I said before, hopefully someone will find this useful. I still maintain that, once the kinks are worked out, it's more detailed than the original.
