-Integration tests for grib2 file loading.
-
-This code used to be part of 'tests/test_grib_load.py', but these integration-
-style tests have been split out of there.
-
-The remainder of the old 'tests/test_grib_load.py' is now renamed as
-'tests/test_grib_load_translations.py'.  Those tests are implementation-
-specific, and target the module 'iris_grib'.
