[cctbxbb] Explicit import for iotbx.pdb.amino_acid_codes

Hello everyone :) I've just started to look into the cctbx facilities, and as i'm a newbie in both object oriented programming and in general to the system, i'm tryng to play around and find by myself how things are working. Using the cctbx.python, i realised that it is necessary to import explicitly the module amino_acid_codes, while for others like atom_name_interpretation this is done straigthforward if you do an import from a lower level (like from iotbx.pdb import *). Is there some good reason because this has to be like that? Thanks in advance for the answer, and excuse me if is it is a question too simple!
