> Sample code:
> NetcdfFile ncfile = NetcdfFile.open(filename);
> Attribute versionAttribute = ncfile.findGlobalAttribute("file_format");
> String fileFormat = versionAttribute.getStringValue();
> System.out.println("GRIB File Format: " + fileFormat);
> 
> Using netcdfAll-v4.2.jar: “GRIB File Format: GRIB-1”
> 
> Using netCDFAll-v4.3.jar: “GRIB File Format: GRIB1collection”
> 
> Is the "GRIB-1" versus "GRIB1collection" values stored within the Grib file
