Summary: region and assembly presented area calulation

Initial Comment:
           BRL-CAD needs a tool to accurately and quickly 
calculate presented area of regions at a given az el, very 
much like 'rtarea' and 'area', but with the capability to 
calculate the presented area of all regions displayed 
individually and an option to find the presented area of 
any assembly that is displayed.  It seems like it should 
be a pretty straight forward adaptation of rtcheck’s 
bookeeping.  Count the number of rays that hit each 
region/assembly, multiply by the pixel size, then list in a 
user friendly way. 

e.g. for regions

Regionname1                xxx.xxxx square units
Regionname2                xxx.xxxx square units
.
.
.

            A useful extension of this tool would be to allow 
the user to parse the data by assembly name.  This 
could be done in two ways: 
1) the sum of the areas of all of the regions in an 
assembly, and
2) the presented area of the assembly as a unit.  
Both of these numbers (and the ratio between them) are 
of use to the V/L community.
