o parameter calendarDumps: when set, approximate months (30-31 days) and years
  (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
  KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
  months and years.  Requires pkg/cal.

394 C Note. 20th May 1998
395 C I made a weird discovery! In the model paper we argue
396 C for the form of the preconditioner used here ( see
397 C A Finite-volume, Incompressible Navier-Stokes Model
398 C ...., Marshall et. al ). The algebra gives a simple
399 C 0.5 factor for the averaging of ac and aCw to get a
400 C symmettric pre-conditioner. By using a factor of 0.51
401 C i.e. scaling the off-diagonal terms in the
402 C preconditioner down slightly I managed to get the
403 C number of iterations for convergence in a test case to
404 C drop form 192 -> 134! Need to investigate this further!
