Thanks Fred! I tried to look through your code and understand what's going
on -- but I'm still at a loss. I'm guessing I need to look at the Django
source to see what should be returned when you hit a URL and what is passed.
The wrapper is confusing me and I've seen that in Django code as well. I'm
going to go out on a limb and say it's probably not as easy as I hoped,
haha.
