I might have given more information/depth than what you were looking for
Thanks Mamta! (And thanks Dan and Mike too)
That was very helpful, and just what I was looking for. I concur with the suggestion to preserve this background information on a set of wiki pages (or in any other form that's convenient); it will be very helpful to future users and maintainers of the code. Mamta, I think your message as you wrote it is a great start for such a wiki page, and then we can go from there. thanks, bryan
