Consider making the repository publicly visible
Right now the repository is internal, so visible to any logged in user. This is appropriate for project that aren't secret, but that the author doesn't want to advertise. Still, we're now facing a problem: we want to install automatically in our computational environment, and that one is fully public. Furthermore, if this repository was public, the installation would become simpler by using pip install git+https://gitlab.kwant-project.org/asantosnet/Poisson_Solver
