[Gmsh] Adding second-order nodes to tet4

[jeremy theler]

Yes, but the difficult part here is to know if a new node needs to be added
or another element already added it, and in such case what is the
already-added node id.

Maybe Gmsh already has this somewhere near the "refine by splitting" tool.
