[phenixbb] Merging Already-Scaled MTZs

Dear Jacob,

it is technically not possible to merge relfection data twice, unless you 
change to a higher symmetry space group: merging means replacing symmetry 
related reflections with their mean.

For scaling this is different - couldn't you repeat the scaling step? I am not 
sure if phenix contains data processing software, I thought it starts at data 
analysis and structure solution.

Cheers,
Tim
