4	! This module excahanges and transforms all fields that should be recieved or sent to
5	! coupler. The transformation of the fields are done from the grid 1D-array in phylmd
6	! to the regular 2D grid accepted by the coupler. Cumulation of the fields for each
7	! timestep is done in here.
8
9	! Each type of surface that recevie fields from the coupler have a SUBROUTINE named
10	! cpl_receive_XXX_fields and each surface that have fields to be sent to the coupler
11	! have a SUBROUTINE named cpl_send_XXX_fields.
