+ Split generate_mesh_2D
+ Offset functions (WIP)

Add toolbox_gmsh to __all__
+ Black

Periodic BCs do not seem relevant for DG function spaces. In addition they may not be supported for DG function spaces for now : https://fenicsproject.discourse.group/t/dg-for-advection-equation-with-periodic-boundary-condition/272
Test for demo_homog2D.py : values of Chom and D# have not changed.
+ Black

Xdmf management

See merge request !3

Including subdomains and with plots.
+ minor corrections linked to the msh_conversion function.

with andling of subdomains and facet regions (can be created with physical groups in gmsh);
+ move msh_conversion function to toolbox_gmsh;

Update demo scripts

See merge request !2

Remove definitions of process_gmsh_log;
use of periodicity classes;
Black

Correction of the values given for constitutive tensors E,E and EGbis,EGbis.

Expression designed for periodic extensionPeriodicExpr is now part of the ho_homog package.Tested with : `demo_pantograph_same_mesh.py`+ Refactoring reconstruction fuction+ minor corrections in geometry sub-package

+ import correction

black for demo_pantograph_mesh

Change name of boolean operations;
Correction name of plot functions;

create the __all__ list;
minor syntax fixes in geometry sub-modules.

Limitations (for the moment) : macro domain must be parallelogram /  parallelepiped with axes aligned with cell periodicity directions; no offset between the origins of the RVE and part coordinate systems.
Test, only for 2D geometry, and demo for pantograph (generate mesh, full scale solving, homogenization then comparison);
+ Black;
+ Activate/Deactivate physical group visibility in gmsh model;
+ Function for mesh conversion .msh -> .xmdf or .xml.

Improve readibility;
Move cross_energy to materials module

Use interpolation rather than projection for reconstruction.
Try to make the reconstruction function compatible with MPI : use of interpolate_nonmatching_mesh_any from fenicstools

Interpolation rather than projection for the displacement solutions of auxiliary problems.

Remove deprecated class, add a missing value_shape method.
 + minor fix for RVE

Move periodic boundary condition class to another file;
Possibility of choosing element (for displacement) and solver settings;
Use of DG elements for strain and stress fields;
Local projection function for DG Functionspace (https://comet-fenics.readthedocs.io/en/latest/tips_and_tricks.html#efficient-projection-on-dg-or-quadrature-spaces)

These functions are no longer redefined in each RVE or part.
Unit test : homogenization of a homogeneous RVE.

EGG scheme, pantograph microstructure, 1×1 RVE.
Support import of xdmf mesh for RVE definition.

Fixes for plots.
