File size: 4304 byte(s) 
Move file cv_thermo.f to directory CV30_routines since it is only used
there. Rename module cv_thermo_m to cv_thermo.

Named constants instead of variables in module suphec_m.

Rename dummy argument spechum of procedure interfsurf_hq to q1lay
(same as corresponding dummy argument in calcul_fluxs).
