[phenixbb] Combine map labels

[Edwin Pozharski]

Not a trivial undertaking, but it can be done.  After all, CNS composite 
omit map does output (optionally) the map coefficients. The way it is 
done there is by doing fourier transform on the output map.  So, you can 
do something along these lines

1. Calculate electron density maps from each of your truncated models.
2. Generate masks for each of your truncated models on the same grid.
3. Combine maps with corresponding masks.
4. Combine all the resulting masked maps.
5. Calculate structure factors from the resulting composite map.

There are definitely programs out there (sfall, mapman, etc) that you 
can use top accomplish this.  This would be a great learning experience 
for you, however if you are more of a practical person and simply want 
to get that final map asap, you are probably better off rerunning your 
composite omit map calculation using one of the following tools
