Fix __init__.py

[mtazzari]

I think we don't need this line since we are not going to support Python v2 anymore:
from __future__ import division, absolute_import, print_function

I think on what we should/could add before closing the issue.

I'd make the changes in a PR, regardless how small it is, so we get it tested before merging into master.

Should we have any imports in there at all?

[jeffjennings]

I don't think they're needed for a few reasons:

• I have all imports in fit.py
• It would be good to have an option to run the code in order to just plot an existing fit
• To run the code the user doesn't necessarily need to import FourierBesselFitter (just FrankFitter)

Ok, that's what I thought too. I'll remove all this stuff and leave an empty init file
