add beginPointWithProcessId and endPointWithProcessId on mesh structure
add parallel info in point entities define on interprocess
fix GeoElement0D::G() and GeoElement0D::vertices() ( depend if a subface or point)
init with invalid value (must be done in mesh construction)
up point info
fix saveGMSHMesh in // but not yet work
if the mesh is build with createSubMesh for example. We need
to have a unique numerotation of point on all process.
So at this time it's work only if the mesh is load from gmsh file format
fix test_importergmsh
