All the maps in the WAD are made up of 10 subfiles.  I know what 
everything in these files is, however, I don't really know what all of 
them are for.  Segs are probably nothing special, and are simply there 
for use by nodes.  At present, I don't know what purpose nodes serve.  
Nodes and sectors are, however, quite closely related.  Exactly how they 
are linked, however, I also do not know.  Reject is a subfile of bits.  
Each bit is a 1 or a 0, and represents some relationship between 2 
sectors.  What is this relationship, though?  These are the questions I 
am currently looking for answers to.  If you can answer any of these 
questions, or think you might, I would really like to hear from you.

Also, I need to come up with a way to determine what sector any given 
x,y map coord. lies within.  If you think you know of a way, let me 
know.  If I can't figure out a way, I will have to resort to using 2 
keys to for "next sector" and "previous sector", and not use the mouse 
at all for this operation.  I don't really like this idea much.

Wow, I guess this file isn't going to be as long as I though after all..
