  Any functional implementation of the DMlibMesh API must compose the following functions with the DM object.
  (See PETSc documentation on PetscObjectComposeFunction(), a polymorphism mechanism.)
  The following functions are called in PetscNonlinear Solver (others can be called by users):
    DMlibMeshSetSystem(), DMlibMeshGetSystem()

  Any implementation needs to register its creation routine, DMCreate_libMesh, with PETSc using DMRegister().
