[Biopython] PDB parser: suppress warnings

[Frederico Moraes Ferreira]

Hi Biopythonees,
Has anybody happen to know how to suppress warnings when reading PDBs 
with hydrogenated waters?

from Bio.PDB.PDBParser import PDBParser
struct = PDBParser().get_structure('tmp', pdbf)

My PDBs came from MD so as all water molecules have hydrogens causing 
thousands of warnings like:
...
/usr/lib64/python2.7/site-packages/Bio/PDB/PDBParser.py:284: 
PDBConstructionWarning: PDBConstructionException: Atom 2H defined twice 
in residue <Residue HOH het=W resseq=2640 icode= > at line 71037.
Exception ignored.
Some atoms or residues may be missing in the data structure.
   % message, PDBConstructionWarning)
...

Thanks in advance.
Fred
