// Based on . CTABLE  structure :
  // FIXME: better to have array instead of object holding longitudes, latitudes members
  //        In the former case, one has to document index 0 is longitude and
  //        1 is latitude ...
  //        In the later case, grid object gets bigger !!!!
  //        Solution 1 is chosen based on pj_gridinfo.c
