Py3 compatibility fixes (Refs: #6)

[mikluko]

Fixes to make all tests pass on Python 3.3 and 3.4.

[pixelogik]

Thx mate! Did you check that this still works with Python 2.7.x?

[mikluko]

Sure. All tests pass on 2.7, 3.3 and 3.4. I added tox.ini to easily run tests on multiple python versions.

I can also try and set up TravisCI if you like.

[pixelogik]

Awesome.

I will check TravisCI for now, because I wanted to use it anyway at some point. I will ping you if I need help.

[pixelogik]

@akabos Hm, there seem to be some issues when running the tests.

For one I added mockredis, because that is needed.

On the other hand past.builtins is not available in Python 2.7? Running the tests failed on my machine saying that. Removing the imports however resulted in multiple fails during the tests.

If you wanna help with that and/or TravisCI, I would be glad.

[mikluko]

@pixelogik Can't reproduce. How exactly you run tests?

[pixelogik]

python run_tests.py

[pixelogik]

I get ImportError: No module named past.builtins

[pixelogik]

(I do not have Python3 installed, just using 2.7)

[mikluko]

That's very strange, because it works perfectly for me in newly created 2.7 venv. Let's ask Travis to run all that and se what he have to say.

[pixelogik]

Ok weird. Maybe my OSX setup is broken :)

[pixelogik]

@akabos Could you help with TravisCI?

[mikluko]

Yup, doing that right now.

[pixelogik]

Awesome

[mikluko]

I'll create new pull request once Travis config is working.

@pixelogik

Having some difficulties running that on Travis (https://travis-ci.org/akabos/NearPy). Installing NumPy and SciPy from sources takes very long time. I found some hints on installing them with conda, but it doesn't seem to work properly. I can't continue today, but I definitely don't give up. I'll keep you updated.

[pixelogik]

Ok. Thanks mate! Looking forward to it.
