!  Purpose and description:

! Control module for the carbon CO2 tracers :
!   - Initialisation of carbon cycle fields
!   - Definition of fluxes to be exchanged
!
! Rest of code is in tracco2i.F90
!
! Le cas online/offline est defini par le flag carbon_cycle_cpl (y/n)
! Le transport du traceur CO2 est defini par le flag carbon_cycle_tr (y/n)
! la provenance des champs (termes de puits) est denini par le flag level_coupling_esm
!
! level_coupling_esm : level of coupling of the biogeochemical fields between

!
! Infofields
! this routine enables to define the field exchanges in both directions between
! the atmospheric circulation model (LMDZ) and ORCHIDEE. In the future this
! routing might apply to other models (e.g., NEMO, INCA, ...).
! Therefore, currently with this routine, it is possible to define the coupling
! fields only between LMDZ and ORCHIDEE.
! The coupling_fields.def file enables to define the name of the exchanged
! fields at the coupling interface.
! field_in_names : the set of names of the exchanged fields in input to ORCHIDEE
! (LMDZ to ORCHIDEE)
! field_out_names : the set of names of the exchanged fields in output of
! ORCHIDEE (ORCHIDEE to LMDZ)
! n : the number of exchanged fields at th coupling interface
! nb_fields_in : number of inputs fields to ORCHIDEE (LMDZ to ORCHIDEE)
! nb_fields_out : number of ouput fields of ORCHIDEE (ORCHIDEE to LMDZ)
!
! The syntax for coupling_fields.def is as follows:
! IMPORTANT: each column entry must be separated from the previous one by 3
! spaces and only that
! field name         coupling          model 1         model 2         long_name
