Thanks for the kind words, guys.
I am glad you find this helpful.

Hi Rich. I do mind that the text content is made available out of my blog. That is mostly because I am working on these articles on a regular basis. This new publication is in its infancy and will be updated significantly very soon. So this pdf will become obsolete within a few days.
Could you please remove the pdf from the forum but replace it with another file that I think will be even more useful to the users?
