[phenixbb] Grid size in max_entropy maps

[Paul Emsley]

Something else that _might_ be useful is to resample the MEM.  In Coot 
you can do so with this "trick": use a combination of a 
standardly-sampled map (with 0 weight) and your MEM (with 1 weight) to 
make an "average" map (Coot uses the first map in the set of maps for 
the sampling of the resulting "average" map).
