  that file to enable user diagnostics, LAMMPS must then be re-compiled
  and re-linked
see the diagnostic.f file for further information on how to create
  routines that operate on internal LAMMPS data, do their own file output,
  perform different operations (e.g. setup and clean-up) depending
  on when they are called, etc
the optional 5th-9th parameters are stored as internal LAMMPS variables
  which can be accessed by the diagnostic routine
