armstrong/armstrong.esi — pull request #17 by philipn (2014-08-17 10:11:48+00:00)
Title: Fixes my install problem.

To reproduce:

```
git clone

virtualenv env
source env/bin/activate
python setup.py install
cd ~/ (or anywhere the module won't be on the current path)

python

> import armstrong.esi
```

Will fail, as the `__init__.py` isn't installed.

I think you all know this namespace packaging stuff better than I do, so please let me know if there's a better solution here!
