[Biopython-dev] Bio.PDB.Structure tests added

[Kristian Rother]

Hi,

I was just running tests on the functions get_chains, get_residues, and
get_atoms in Bio.PDB.Structure. It all seemed fine, and I decided to
create a branch with test functions, because I didn't find any so far.

(the testing included manually counting through the atoms. I recognized
that there are some specific rules how insertion codes are interpreted
(e.g. always takes the second residue), but they seemed consistent to me.
