!IDEAL:MODEL_LAYER:INITIALIZATION
!

!  This MODULE holds the routines which are used to perform various initializations
!  for the individual domains.  

!  This MODULE CONTAINS the following routines:

!  initialize_field_test - 1. Set different fields to different constant
!                             values.  This is only a test.  If the correct
!                             domain is not found (based upon the "id")
!                             then a fatal error is issued.

! this is a wrapper for the solver-specific init_domain routines.
! Also dereferences the grid variables and passes them down as arguments.
! This is crucial, since the lower level routines may do message passing
! and this will get fouled up on machines that insist on passing down
! copies of assumed-shape arrays (by passing down as arguments, the 
! data are treated as assumed-size -- ie. f77 -- arrays and the copying
! business is avoided).  Fie on the F90 designers.  Fie and a pox.
