! Changes due to new module structure of the plant canopy model:
!   module plant_canopy_model_mod added,
!   new package/namelist canopy_par added, i.e. the canopy model is no longer 
!   steered over the inipar-namelist,
!   drag_coefficient, leaf_surface_concentration and scalar_exchange_coefficient
!   renamed to canopy_drag_coeff, leaf_surface_conc and leaf_scalar_exch_coeff.
! Changed statement tags in CONTINUE-statement
