This MR removes the compatibility with python 2 and adds the capability to easily link another code to waves using CMake, as well as a feature to read results from the disk.
Changes
Remove all import from the future libs of python, the code is now compatible with python 3 only
Add a waves-config file allowing to easily find and link waves to another code using CMake
Add a load method to GmshImport to read results from the disk (restart/checkpoint feature)
Add a UnitTest class to test the classes and methods in tbox which can not be accessed directly through python
Rename katropton to katoptron, although this was done in !59 (merged), it was not referenced by a tag
Various minor cleaning and bugfixing
Comments
The GmshImport and GmshExport classes need to be upgraded to deal with gmsh format 4, as well as to read and write data in binary
The new method GmshImport::load contains a lot of repeated code, similarly to GmshExport::save, there might be a way to improve this
Tests
Passed on ubuntu20.04 (python 3.8.2), and msys2 (python 3.8.1).
