As I mentioned on my blog, I've entered graduate school and it's occupying all the time I can give it, so at least until the semester ends I don't expect to be able to report any significant progress, if I even manage to get any work done on this project at all; and until the program ends, I expect time invested and progress shared here to remain minimal. I'm just posting this log here to let anyone who comes by and might be interested know that I haven't given up, but sadly don't expect to be very active with this for a while. In the meantime, thanks for your interest and patience!
