Subject: [PATCH] pymatbridge/pymatbridge.py: Older versions of NumPy don't
 supply the tobytes method. However, it is stated in the NumPy release notes
 for 1.9.0 ( http://docs.scipy.org/doc/numpy/release.html ) (
 https://github.com/numpy/numpy/blob/master/doc/release/1.9.0-notes.rst ) that
 this behaves the same as tostring. So, this workaround tries to use tostring
 if tobytes fails.
