How to create SST on regional mercator grids using ieee2grib_sst.F?

This is a very "quick and dirty method of creating SST grib file for your regional domain on the mercator projection".
This uses "libs/etc/utils/ieee2grb_sst.F"

1. My application name is, say, "tatl", meaning "tropcal atlantic ocean regional domain".
2. cp ieee2grb_sst.F to ieee2grb_sst_tatl.F
3. change in the ieee2grb_sst_tatl.F..
