FiPy only understands Gmsh's msh2 format and Gmsh 4.x does not export ghost cells correctly in msh2.

  • This constraint should be documented
  • FiPy should support newer Gmsh formats

Document that FiPy can't use Gmsh >= 4.0 for partitioning

- Limit Gmsh to < 4.0
  Gmsh 4.0 doesn't partition correctly
  Addresses usnistgov#697
- Export ghosts with Gmsh 4.x
  [Ghosts are broken](https://gitlab.onelab.info/gmsh/gmsh/issues/733),
  but export them anyway.
- Change refinement metric
- Limit refinements
  Gmsh refinement seems to stall out
- Don't partition tiny meshes
- Tolerate mangled Gmsh version string

  Assume Gmsh 3.0 if we can't parse the useless nonsense
  that Gmsh stuffs into stderr
- Ensure GmshMesh uses correct communicator

  More than one overlap will "downgrade" to a serial communicator
  because Gmsh doesn't give us more than one layer of ghosts
