I don't know how to use the "Pastis-NB" model

Thank you very much. I noticed that the author developed a better "Pastis-NB" model. And said:“A Python implementation of Pastis-NB is available at https://github.com/hiclib/pastis under the BSD license”. However, unfortunately I only found the pastis-mds, pastis-nmds, pastis-pm1, pastis-pm2, pastis-poisson models and not found the Pastis-NB model in the Pastis.
so, I don't know how to find and use the Pastis-NB model in the Pastis to build a 3D structural model.
