#368 closed enhancement (fixed)

Diag nep has not the same convention as the other carbon fluxes

All carbon fluxes output from stomate_lpj have the convevtion positive from atmosphere to land. But nep, output from stomate has the opposite sign.
In stomate :

       co2_flux_daily(:,:)=   &
            & resp_maint_d(:,:) + resp_growth_d(:,:) + resp_hetero_d(:,:) + &
            & co2_fire(:,:) - co2_to_bm_dgvm(:,:) - gpp_daily(:,:)

     CALL xios_orchidee_send_field("nep",SUM(co2_flux_daily*veget_cov_max,dim=2)/1e3/one_day)

In stomate_lpj :

    CALL xios_orchidee_send_field("nbp",(SUM((gpp_daily-(resp_maint+resp_growth+resp_hetero)-co2_fire) * &

To be consistent, we propose to change sign for nep.
Note comments in field_def_orchidee.xml rev [4318] are correct.

ORCHIDEE DAY 2017 : we change the sign of nep. At same time we change the name of the variable co2_flux_daily into nep.
