- remove OLD_EXF_INTERP_LAT_INDEX code ; - move interpolation into separated S/R and file: exf_interpolate.F - extended input field (2 rows) near the N & S poles:  * fill in with the symetric value (when even Nb of data in longitude)  * add average value at the poles only for scalar quantities (for vector    component interpolation, skip the averaging and keep duplicated values) - add argument myIter and add debug print on 1rst iter if debugLevel >=2
