Changeset 850

Add CONTFRAC on SECHIBA monitoring to have true values in couple model.

To compare to similar variables in LMDZ monitoring, you should remember that :

• evap is not in a SI unit : mm/d = kg/m2/s * 86000 .
• ORCHIDEE has a delay of one time step with respect to LMDZ in the GCM (3-4 % error).

VEGETFRAC and MAXVEGETFRAC are monitored only for mean of agriculture pfts to see land use update.
