ImportError when installing in editable mode

[cartacamilla]

Hi, thanks for this package.

I was having issues when installing your package in editable mode with pip install -e .

Instead of being able to import facenet_pytorch, I could only import each main folder (models, data, dependencies). The problem is that the structure of the repo is non standard. I made the necessary changes and it is now working for my purpose. Let me know if you would be interested that I make it into a pull request.
