Data in sequential I/O files
Input files:
1. msh_bc_xyz.tmp, for every node give
   packed_binary_integer_BC_flag, x-coord, y-coord, z-coord 
2. msh_typ_nodes.tmp, for every element give
   integer_element_type, connectivity list
3. msh_ebc.tmp, for every essential BC (if any) give
   node number, local DOF number, value assigned
4. msh_nbc.tmp, for every non-zero point source (if any) give
   node number, local DOF number, value assigned
5. msh_mixed.tmp  not used as of March 2006

Nodal output files:
1. node_results.tmp, for every node gives
   list of values of each local DOF
2. node_reaction.tmp, for each EBC assigned give
   node number, local DOF number, value assigned, eq. number

Element output files:
1. el_qp_xyz_fluxes.tmp, for every element loop over each
   of its n_q quadrature points and give
   quadrature pt. coordinate(s), flux component(s)
