Thank you. I think I can find introductory materials on my own. This is now on my list of things about which I'd like to learn/relearn more. It's been a long time since I've had any superficial exposure to the topic; my recollection of it is vague and in all likelihood outdated. My memory is a bit "situational" -- I tend to remember best the things I've been thinking about and working on, but as time passes everything else sort of becomes blurrier, less precise in my mind.
