Title: pypy support for Bio.PDB

I'm pypy you can't import Bio.PDB after import numpypy because linalg is not implemented. This lines solves the problem:

try:
# Superimpose atom sets
from Superimposer import Superimposer
# Kolodny et al.'s backbone libraries
from FragmentMapper import FragmentMapper
except:
# Problem with pypy, don't support for numpy.linalg
pass
