download-all-tutorials does perhaps not belong in the templates

[henrikjacobsenfys]

I got this feedback from a user

"if I execute the command "python -m easydynamics download-all-tutorials" I get the error "'easydynamics' is a package and cannot be directly executed". I downloaded the jupyter notebooks from the github page but then I think still miss some things to run them properly, i.e. I don't get the vanadium example file that you use in some of your examples"

(it's here in dynamics: https://easyscience.github.io/dynamics-lib/0.2.0/installation-and-setup )
