 * FEM Mesh
 * Gmsh object is a mesh object, which allows using the Gmsh meshing tool inside FreeCAD. Various options of Gmsh are supported.
 * Boundary layer object for gmsh makes it possible to create boundary layer.
 * Mesh group object for gmsh makes it possible to create nodes and element groups. The names can be changed by the user.
 * Mesh region object for gmsh makes it possible to define mesh regions with different mesh element sizes for nodes, edges, faces and volumes.
 * GUI clear mesh tool clears the mesh but keeps all mesh adjustments. This is very handy if files should be shared.
 * GUI print mesh info tool print all kinds of mesh information.
 * GUI mesh view provider is able to display quad face mesh as well as hexahedron, pentahedron and pyramid mesh elements.
 * Mesh data model was updated to use SMESH version 7.7.1 https://github.com/FreeCAD/FreeCAD/commit/666a3e5a
 * Mesh API was extended to allow Python to read mesh group data out of the FreeCAD SMESH FEM mesh data. This was the base for the Gmsh group object.
 * Mesh API was extended to export mesh groups to Abaqus and CalculiX inp file format.
 * FEM mesh 2 mesh tool converts a surface of a volume mesh into a mesh for FreeCAD's mesh module.
 * Mesh problems: Non-positive Jacobians are an often seen problem in FEM meshes. Elements which have non-positive Jacobians in CalculiX solver are colored in FreeCAD.
 * Fenics Import and export of Fenics mesh format has been added.
