Jupyter notebook examples out of date?

[AnjaConev]

Hi,

I've been trying to run your jupyter notebook examples and I think that they are a little bit out of date with the current version of your hotspots packaged.

I am running fragment_hotspot_maps.ipynb

When running the second cell, in particular the import

from hotspots.hotspot_calculation import Hotspots

I get an error:
ImportError: cannot import name 'Hotspots' from 'hotspots.hotspot_calculation'

And I see that there is no hotspot_calculation module in hotspots package.
Am I doing something wrong or are the notebooks not in compliance with the current version of the hotspots package?
