`pip install -e .` does not work in a new Python environment

[romanwerpachowski]

When I try to install blanc in a new Python environment using pip install -e ., this fails because the installation process requires nltk and torch to be present during installation.

[romanwerpachowski]

It's possibly because of this line in setup.py:

from blanc.version import version

which triggers importing many other blanc modules.

Thanks! I will look at this anyways, appreciate if you could give the exact error message you got.

Suggested fix in #37.
