42   DMMoabOutput - Output the solution vectors that are stored in the DMMoab object as tags
43   along with the complete mesh data structure in the native H5M format. This output file
44   can be visualized directly with Paraview (if compiled with appropriate plugin) or converted
45   with tools/mbconvert to a VTK or Exodus file.
46 
47   This routine can also be used for check-pointing purposes to store a complete history of
48   the solution along with any other necessary data to restart computations.

50   Not Collective
51 
52   Input Parameters:
53 + dm     - the discretization manager object containing solution in MOAB tags.
54 .  filename - the name of the output file: e.g., poisson.h5m
55 -  usrwriteopts - the parallel write options needed for serializing a MOAB mesh database. Can be NULL.
