File size: 3926 byte(s) 
Changed unit of variables lat_min_guide and lat_max_guide from module
conf_guide_m from degrees to rad. Then we do not have to convert the
whole array rlat from rad to degrees in SUBROUTINE tau2alpha.

Removed some useless computations in inigeom.

Removed module coefils. Moved variables sddv, unsddv, sddu, unsddu,
eignfnu, eignfnv of module coefils to module inifgn_m. Downgraded
variables coefilu, coefilu2, coefilv, coefilv2, modfrstu, modfrstv of
module coefils to local variables of SUBROUTINE inifilr.

Write and read a 3-dimensional variable Tsoil in restartphy.nc and
startphy.nc instead of multiple variables for the different
subs-urfaces and soil layers. This does not allow any longer to
provide only the surface value in startphy.nc and spread it to other
layers. Instead, if necessary, pre-process the file startphy.nc to
spread the surface value.
