M 265 libf/phymars/physiq.F
<> Added a PBL section for outputs, with a call to SL outputs via surflayer_interpol and thermals outputs

A 0 libf/phymars/surflayer_interpol.F
<> New subroutine to interpolate horizontal velocity norm and potential temperature in the surface layer.

THIS ROUTINE IS NOT VALIDATED YET. IT IS TURNED OFF BY DEFAULT AND IS HERE FOR DEVELOPMENT PURPOSES ONLY FOR NOW.

M 265 libf/phymars/vdif_cd.F
<> Important modification to the Reynolds formula : due to a confusion of symbols used in the litterature, a wrong simplification of

numerical values had been implicitely done... It is now corrected and yields better results for the mixed layer temperature.

M 265 libf/phymars/vdifc.F
<> Cosmetic modif (added comment for more clarity)

 - vdifc.F Now takes into account sub-grid gustiness, evaluated from thermals activity (it's proxy being the maximum vertical velocity)
 - Minor modification in meso_inc_les.F: u* is now taken from the new vdifc and not recomputed from a simple law

+- Formula correction for the Reynolds in vdif_cd : will affect the thermal roughness length. Results obtained with the precedent formula (previous commit) probably underestimate by about 1K the temperature in the mixing layer.
+- Added a new subroutine to libf/phymars called surflayer_interpol.F. This routine can be called as a diagnostic for interpolation of horizontal velocity norm and temperature in the surface layer, in 1D or 3D. The output height is controlled by a parameter z_out, to be set in physiq.F. This might be later added to a .def file. z_out is set to 0. by default, resulting in no call to this subroutine.
