New organisation of functions designed for generating periodic meshes.

Use of the function designed to import a mesh with xdmf format.

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.

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

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.

Trailing spaces / empty lines / spaces/try-except conventions + change behavior of gemetry reset function.

Unit tests for this class.

Reorganizing and simplifying the logging.  One logger per homog file and only 2 handlers which are associated to the root logger.

Generalizing the use of Path rather than mesh file names (strings).

Weak material domain of the RVE is now obtained by a boolean cutting operation and not an intersection anymore.\n
Static method to get the boundary of a group of surfaces seen as a single entity.\n
Mesh refinement methods have been consequently corrected. \n

The static method gmsh_2_Fenics_2DRVE that create FEniCS objetcs from gmsh objects has been completed. \nBasic tests with plots. \nIn addition to the mesh, physical regions and facets regions are imported.

Option Mesh.SaveAll has to be set to 1, otherwise the conversion with dolfin-convert fails.
New set_gmsh_option() function for more consistent changes of gmsh options.

Test of this function succeeded.

pantograph, auxetic squares and pantograph of beams.

Only Point instances can be used as attractors for now.

In the class constructor,  only one set of generating vectors is saved. \n
Refactoring in the class constructor.

Insert the synchronize() call in the Fenics2DRVE class to partially correct the mesh refinement error.  \n
Cleaning in create_mesh. \n
Adding synchronize() call in the add_gmsh method of PhysicalGroup in order to see all the physical groups in the model.

Make all lineloops that define the geometry have the same orientation in the pantograph staticmethod. \n
Cleaning of the create_mesh file.

Refactoring. The boolean operation have been changed to static methods of the AbstractSurface class.

doesn't modify the input list in place.
