5      ==============================      ==============================
6    
7  o pkg/exf (interpolation):  o pkg/exf (interpolation):
8      - extended input field (2 rows) near the N & S poles:
9        * fill in with the symetric value (when even Nb of data in longitude)
10        * add average value at the poles only for scalar quantities ; for vector
11          component interpolation, skip the averaging and keep duplicated values,
12          unless the 2 components have same location (uvInterp=T) in which case
13          interpolate the 2 components together using S/R EXF_INTERP_UV.
14      - new S/R EXF_INTERP_UV to interpolate the 2 components of a vector field
15        together: this allows to account properly for local orientation when
16        averaging at N & S pole.
17      - add CPP option EXF_USE_OLD_INTERP_POLE to recover old results regarding
18        exf-interpolation near N & S poles. Undef by default.
19      - add debug check/print on 1rst iter if debugLevel >=2.
20    o pkg/exf:
21      - change masking flags definition (no longer "parameter"), put them in
22        common block and set them in S/R EXF_INIT_FIXED.
23      - change recognized masking flag from s,u,v to c,w,s since the mask
24        to use (maskC,W,S) depends on position on model grid and has little to
25        do with scalar/vector difference; fix masking if using P-coordinates.
26      - fix masking of wind-stress (was wrong if interpolated or read on A-grid)
27        and update results of exp. global_with_exf (x2).
28      - fix setting of zenith-angle table when SHORTWAVE_HEATING is undef.
29    o pkg/obcs
30      - S/R obcs_calc_stevens: fix a small bug (gammat -> gammas where appropriate)
31    o pkg/exf (interpolation):
32    - assume periodicity in X only if input field cover full longitude range.    - assume periodicity in X only if input field cover full longitude range.
33    - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,    - improve search for lat. index (supposed to be faster, in ~log2(ny) steps,
34      and should vectorise).      and should vectorise).
