[phenixbb] resolution bins

Hi Daniele,

the number of resolution bins is determined automatically to allow a 
significant number of test reflections per bin (that is enough to: - 
estimate ML parameters, - compute Rfree). The default value is 
"free_reflections_per_bin=140" which is found empirically (by running 
many refinement trying different values) to be the best.
