5      ==============================      ==============================
6    
7    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:  o pkg/exf:
21    - change masking flags definition (no longer "parameter"), put them in    - change masking flags definition (no longer "parameter"), put them in
22      common block and set them in S/R EXF_INIT_FIXED.      common block and set them in S/R EXF_INIT_FIXED.
