[Therion] Build a map with all centerline and partial walls

[Bill Gee]

I thought of doing that, then decided not to.  It would be fairly easy 
to create a basic sketch, scan it and then generate scraps.  However, 
when the passage finally is sketched for real I would have to start all 
over.  That is more than I want to keep track of.

The solution of "walls off" in the centerline/endcenterline group is 
exactly what I wanted.

Having thought about it overnight, it occurs to me that having the LRUD 
displayed might actually be a Good Thing!  It points out two things - 
The LRUD data does not match the sketch, and there are probably some 
errors in the LRUD data.

I see several places where a very large triangle sticks out in to open 
space.  Looking at the data for one of those survey legs, I see a 
left=34.0 in the notes.  It probably should be 3.40.  The original notes 
are very clear about 34.0.  Clearly an item to go back and double-check.
