[cctbxbb] reduce2 and cell construction from python script

Hi, I apologize for the naive post. I am trying to figure out how to perform the following tasks: 1) read in a mmcif file (which I think I can do following the tutorial); 2) trim the solvent and hydrogen atoms (probably I can do it following the tutorial); 3) run reduce2 to get hydrogens in the nuclear positions (no clue); 4) get the full content of the unit cell (no clue). Any help is appreciated. All the best, Enrico
