Please improve the scripts/exrtofs_glo_ncoda_inc.sh script hycom_var restart file checking as followings -

background -
In scripts/exrtofs_glo_ncoda_inc.sh, when either one hycom_var seatmp or salint or uucurr or vvcurr or lyrprs or icecov files are missing, job proceeds with WARNING message, but fails later at $EXECrtofs/rtofs_raw2hycom or $EXECrtofs/rtofs_ncoda_archv_inc. If these hycom_var restart inputs are critical, it should fail the job with FATAL ERROR message, instead of WARNING message.

Please improve the scripts/exrtofs_glo_ncoda_inc.sh script hycom_var restart file checking with FATAL ERROR message when they are not available and fails the job at right place.

[DanIredell-NOAA]

Modified scripts/exrtofs_glo_ncoda_inc.sh to check for required hycom_var files. If any do not exist then exit with a fatal message.
