!---------------------------------------------
! Initialize route handles in the mediator and also
! initialize unity normalization fields and do the mapping for
! unity normalization up front
!
! Assumptions:
! - Route handles are created per target field bundles NOT
! per individual fields in the bundle
! - ALL fields in the bundle are on identical grids
! - MULTIPLE route handles are going to be generated for
! given field bundle source and destination grids
! - Route handles will ONLY be created if coupling_active is true between n1 and n2
! Algorithm
! n1=source component index
! n2=destination component index
! nf=field index
! fldListFr(n)%flds(nf) is queried to determine the mapindex and mapfile
! and the appropriate route handle is created
!
! Regridding is done on a per-field basis AND only for those fields that have a
! valid mapping index for the destination component
! n = source field index field index
! destcomp = destination component index
! The fldsSrc input argument is queried for the mapping type of the field
! for the desination component
! mapindex = fldsSrc(n)%mapindex(destcomp)
! If the mapindex is 0 (there is no valid mapping) then NO mapping is done
! for the field
