[Biopython-dev] Features of the GSOC branch ready to be merged

[João Rodrigues]

Adding to the build_biological_unit question. I re-wrote it to create a new
structure and not to use deepcopy. A very crude benchmark (running two
versions of the function) shows this:

New function (w/out deepcopy):
real    1m26.078s
user    1m21.993s
sys    0m2.048s

Old function (w/ deepcopy):
real    2m15.544s
user    2m9.105s
sys    0m3.092s

So... a slight improvement I'd say. Pushed it to the pdb_enhancements branch
as a new function called apply_transformation_matrix. A perhaps more
descriptive and explicit name to the function.

Cheers,

João
