QBSP still bites

Not much to report... since I took a whole month away from the editor. I took another stab at getting something done last night - no luck =(. I'm sure I will finish the map eventually, but it's going to be a fight all the way. If anyone wants to volunteer and apply some numerical analysis skills to the algorithms in qbsp (which I think must have some serious problems), then please do and let me know.
