Versioning becomes consistent at this point (prior to this release the version number in setup.py followed a `0.4.a` convention while the version in `__init__.py` follows a `0..0` convention. Due to this the version numbers are enumerated here but are not mutually exclusive).
0.5.0
0.4.3a
0.4.2a
This version number is in both `__init__.py` and setup.py until setup.py changes to 0.4.3a
0.4a1
setup.py` is created and the package is made installable
