Could you maybe be a bit less cryptic and name your institute/university also ?

[Alexander Kozlov]

Which field should it go to? I don't see institution/university/full names in other packages. If there is no dedicated field, I can write it in the class docstring, for example.

[Lia Domide]

you are perfectly right. Still, to have some details in the docstring would seem of great benefit to me. What do you think ?

[Alexander Kozlov]

Sure, you can add this line to the docstring: "Developed by Alexander Kozlov (akozlov@kth.se), KTH Royal Institute of Technology, Stockholm, Sweden". Or should I create another pull request?

[Lia Domide]

as this was not yet merged, it could be an extra commit still here, I think

[Alexander Kozlov]

Just committed.

[Lia Domide]
