If you like to review the presentation I made this evening, February 23, 2010, you will find the information on my site. I recommend that you watch the slide show one slide at a time with full effects, showing the transition from one state to the next. The PDF files are for convenience and for printing if you like. You may ask questions if you have any; if you do, please do so where the post is on my site so the questions and answers have context and accumulated information.
