Issue with pyvoro as distributed on pypi

When running the main.py file:

import pyvoro

print('success?')

(test_env) .../test$ python3 main.py
Traceback (most recent call last):

I get the same error regardless of whether I install via pip or from source

@Nagnar @peder2tm : This module is only Python 2, and will not build with Python 3.

Previous issues:
#8

Some work was done to port it to Python 3:
#11

In the meantime, I also made a similar library that should work on python 3: http://tess.readthedocs.io/

@wackywendell
I see, the source I used which worked was the python3 feature branch.
Tess is 3d based and the docs don't mention using it for 2d so would I be able to use it for that?
