     27'''   (I.0)''' standardisation of the name of quantities derived from horizontal scale factors (many modules of NEMO)[[BR]]The chosen names of quantities derived from horizontal scale factors are:[[BR]]- inverse of scale factors : r1_e1t, r1_e2t, r1_e1u, r1_e2u, r1_e1v, r1_e2v, r1_e1f, r1_e2f ;[[BR]]- surfaces and their inverse:    e1e2t, e1e2u , e1e2v, e1e2f  and, r1_e1e2t , r1_e1e2u , r1_e1e2v, r1_e1e2f ;[[BR]]- ratio (used in traldf...) : e2_e1u , e1_e2v(I.1) generalize of the use of surface scale factors ;[[BR]]These quantities are defined in memory in dom_oce.F90, and set to their proper value in domhgr.F90

    29 (I.2) add a optional read of surface scale factors in coordinate file (domhgr.F90)[[BR]]        The input coordinate file have to include e1e2u and e1e2v in case of reduction of the scale factors in some straits.[[BR]]      When e1u or e2v are reduced in some straits, the surface at u- and v-points remains unchanged.[[BR]]    This allows to suppress the dom_vvl_orca_fix routine.

We kept here the hard coded reduction of scale factor in some straits for some given ORCA configuration. [[BR]]A last step (see IV) will be to suppress the hard coded reduction of some scale factor as it will be always given in the coordinates.nc file together with the e1e2u & e1e2v surfaces.
