Python 3

[Jonathan MacCarthy]

Hello Pisces users,

I apologize for the bulk email, but want to check in with everyone regarding Python 3 usage.  I've got a working Python 3 _only_ version of Pisces (not dual Python 2 and 3), and I wanted to see how disruptive it might be for anyone if I release it as v0.3.0.  The last Python 2 version is tagged v0.2.4, and will still be available from github using that tag, or from PyPI as version 0.2.4, but I'd like to proceed with the Python 3 version.

Python 2.7 will die in two years, and NumPy will stop supporting it even sooner.  Pisces was the only thing holding my work from moving completely to Python 3, and I'm ready to do so.  Since a Python 2 version will always be available as v0.2.4, I'd like to leave Python 2 behind in the next release, which is ready to push.  Does anyone have any strong objections?

Thanks again,

Jon
