Importing fails!

You can install the project from PyPi (or locally), but when you try to use it, it fails out on an error related to relative pathing:

The file exists in that relative path in the repo, but I think it might not be being installed by the package because it is not listed in the packages key in setup.py:

packages=['iiif_prezi3', 'iiif_prezi3.helpers', 'iiif_prezi3.extensions'],

A quick change locally to add the config dir seems to confirm that it fixes the issue - PR incoming
