9	! initialize_field_test - 1. Set different fields to different constant

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