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

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

 49:   Collective

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