A note to those who are browsing this presentation on the web

Advance from slide to slide using the "<" and ">" at the top and bottom of each page. ">" links to the next slide and "<" links to the preceding slide.

In giving the presentation, I sometimes wander througn various links in a sequence that is not recorded in these pages, and there are several comments that are not referenced in the text of the slides; browsing the slides gives the flavor of the presentation, but is not the same as seeing the whole show.
