Proper pip package

[CBockelmann]

I'm currently using your work to illustrate cs algorithms via jupyter notebooks. However, the installation of your code is not as straightforward as it could be. Currently, you need to install via

pip install -e .

or it wont work, because pip does not copy any files. Please fix the setup.py such that one can simply do

pip install git+https://github.com/GAMPTeam/vampyre.git

This would enable simple installation also directly via juptyer magic like

%pip install https://github.com/GAMPTeam/vampyre.git

In a notebook to run notebook files anywhere (like the nbviewer public service)
