[Therion] Therion Theory - scrap and map definitions

[Vasily Vl. Suhachev]

Hello Bruce and All

I had to draw a few large caves and I want to share my experience:

1) I always keep scanned survey notebooks. This is an artifact obtained 
in a cave and is the source of truth.

2) I store the entire centerline in a separate directory with a split 
into files on a trip basis. I think this is more correct because the 
centerline is a direct reflection of the survey notebooks. In the case 
of an error, this allows you to quickly navigate to notebooks. Entire 
cave centerline assembled in index file inside centerline directory.

3) I do not tie maps tightly to survey trips because it's usually more 
convenient to draw a map that covers a cave part (passage, grotto) 
rather than surveying trip.

I call such dedicated part of the cave as `subsystem`. Subsystem maps 
are stored in separate subsystem directories. In each directory there 
are files `thconfig`, * .th2 and a file `maps.th` in which the 
definition of maps and joins is stored.

I store the definition of maps of the entire cave in the top directory 
in the `maps.th` file in which I connect the` maps.th` files from the 
subsystems' directories. I do not use therion namespaces for maps 
because the number of maps are much smaller than the surveys. Uniqueness 
of names of maps I support manually.

Folder structure example:

cave
     +-- survey# scanned notebooks
         +-- trip1
             +-- 1.jpg
             +-- 2.jpg
         +-- 3.jpg
     +-- trip2
     +-- trip3
     +-- trip4
+-- cl                        # centerline
         +-- cave.th               # index file with equates
         +-- trip1.th
         +-- trip2.th
         +-- trip3.th
         +-- trip4.th
     +-- model
         +-- thconfig
     +-- map
         +-- p                     # plan
             +-- subsystem1
                 +-- 1.th2
                 +-- 2.th2
                 +-- maps.th
                 +-- thconfig
             +-- subsystem2
                 +-- 3.th2
                 +-- maps.th
                 +-- thconfig
             +-- maps.th
             +-- thconfig
         +-- rr                     # extended elevation
         +-- r240                   # elevationat 240
