 37:   DMMoabOutput - Output the solution vectors that are stored in the DMMoab object as tags
 38:   along with the complete mesh data structure in the native H5M or VTK format. The H5M output file
 39:   can be visualized directly with Paraview (if compiled with appropriate plugin) or converted
 40:   with MOAB/tools/mbconvert to a VTK or Exodus file.

 42:   This routine can also be used for check-pointing purposes to store a complete history of
 43:   the solution along with any other necessary data to restart computations.

 45:   Collective

 47:   Input Parameters:
 48: + dm     - the discretization manager object containing solution in MOAB tags.
 49: .  filename - the name of the output file: e.g., poisson.h5m
 50: -  usrwriteopts - the parallel write options needed for serializing a MOAB mesh database. Can be NULL.
