Could not run `python3 -m vecino --help`

[bzz]

Sorry if I have missed something, but after working around #1 on running python3 -m vecino --help (by analogy with https://github.com/src-d/ast2vec/) I got

python3 -m vecino --help
Traceback (most recent call last):
  File "/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/runpy.py", line 183, in _run_module_as_main

Allthough README does not mention it, from vecino/main.py#L10 It looks like CLI is an intended usage of Vecino.

Works.
