Merge branch 'release-0.1.5' into develop
* updated the setup.py to use setuptools to avoid issues with the egg-info files. This was a bit trickier because of the cython code.
* also discovered compilation bug when linking to a static hdf5 library (version 1.8.11 or higher) and made a note in the README
* the bug comment did not belong in the README... I've added it as an issue to the repository instead
updated version to 0.1.6, updated NEWS
Merge branch 'release-0.1.6'
