      The input and output files use the simple TABLE format;
      comment lines begin with a "#" character.  Otherwise, each line
      of the file contains one set of information, either the coordinates
      of a node (for a node file), or the indices of nodes that make up
      a tetrahedron, (for a tetrahedron file).
