  C     *==========================================================*
  C     | SUBROUTINE THE_MODEL_MAIN
  C     | o Master controlling routine for model using the MITgcm
  C     |   UV parallel wrapper.
  C     *==========================================================*
  C     | THE_MODEL_MAIN is invoked by the MITgcm UV parallel
  C     | wrapper with a single integer argument "myThid". This
  C     | variable identifies the thread number of an instance of
  C     | THE_MODEL_MAIN. Each instance of THE_MODEL_MAIN works
  C     | on a particular region of the models domain and
  C     | synchronises with other instances as necessary. The
  C     | routine has to "understand" the MITgcm parallel
  C     | environment and the numerical algorithm. Editing this
  C     | routine is best done with some knowledge of both aspects.
  C     | Notes
  C     | =====
  C     | C*P* comments indicating place holders for which code is
  C     |      presently being developed.
