Hello!
I was trying to run the "Grids" example notebook, but I get an import error in the first cell:
ImportError: cannot import name 'GridArray' from 'nata.containers'

I did some tests in the interactive shell, and from nata.containers import * works fine, but it apparently doesn't import the GridArray class:

I noticed the same kind of error with from nata import examples, by the way.
Any idea what this could be about?
Thank you!
