Get always closer to 4.0

Many new things: anisotropy, spatial dispersion (nonlocality). Everything should be documented and tested.

Not clean or complete enough to be declared 4.0 but almost... please use, test and enjoy.

A major change in the way materials are managed. Open the way to use extensive material libraries.

Full Changelog: 3.14...3.2

Resub' release

Several updates make the code and its accompanying material (the notebooks) ready for publication in an academic journal.

PyMoosh 3.1

PyMoosh is a Python-based simulation library designed to provide a comprehensive set of numerical tools allowing to compute essentially all optical characteristics of multilayered structures, ranging from reflectance and transmittance to guided modes and photovoltaic efficiency. Optimization tools are also included. PyMoosh is designed not just for research purposes, but also for use-cases in education. To this end, we have invested significant effort in ensuring user-friendliness and simplicity of the interface.

This release corresponds to version 3.1, it is considered fully ready and tested. In future versions, only new features will be added.
