  Grid-restructuring (also called domain-decomposition or multi-
  blocking) allows parts of grids to be moved from their usual
  positions and linked with unusual neighbours. The advantage is
  that irregular shapes can then be fitted without significant
  waste of computer storage or execution time.

  The method is here illustrated for a simple rectangular shape
  which has one part shifted relative to the other, as indicated.

  LSG58=T, so as to ensure that BFC=T for display purposes only,
  ie in SATELLITE and PHOTON, but BFC=F in the EARTH run, because
  the grid is cartesian. This saves much storage.
