Fix names of x,y coordinates fields in iom_nf90.F90
Similarly to MR !33 (merged), the files produced by the call to iom_nf90.F90
, e.g. for the default mesh_mask creation,
assign the same name 'x' and 'y' to both dimensions and coordinates.
Adding the correct name to coordinates fields, namely nav_lat
and nav_lon
, will simplify the handling of these files, e.g. with python packages such as xarray
(see also !32 (comment 263)).
