test.py doesn't run

[KirkEasterson]

OS: Kubuntu 20.04

To recreate:

git clone https://github.com/nanomsg/nnpy.git
cd nnpy/nnpy
python tests.py

This produces the output::

Traceback (most recent call last):

ValueError: Attempted relative import in non-package

This is because the directory that the tests are being run in takes precedence for imports and class declarations. This can be observed in the lines:

...
  File "/usr/lib/python2.7/email/utils.py", line 28, in <module>
    import socket
...

There are three options:

1. Move test,py to nnpy/
2. Create an nnpy/test/ directory and move it there
3. Create an nnpy/nnpy/test/ directory and move it there

I think option 3 is preferable

Have you tried running python setup.py test from the top-level directory, instead?
