DESCRIPTION OF CHANGES:

Modify chgres_cube to output files in netcdf4 (and not netcdf4-classic).

TESTS CONDUCTED:

The consistency tests were run on Hera, Jet, Orion and WCOSS2. All tests failed (according to the nccmp utility) because the baseline files were netcdf4-classic. That was the only difference. All data values were the same. This result was expected.

DEPENDENCIES:

None.

DOCUMENTATION:

N/A

ISSUE:

Fixes #689.

Will merge, then update the consistency test baseline files on all machines.

This change loses the NF90_CLASSIC_MODEL flag, and that's fine.

The CLASSIC_MODEL flag ensures that the created file follows netCDF classic rules, so it can be processed by netcdf-classic (i.e. pre-netCDF4) code. Although the CLASSIC_MODEL enforces some restrictions on the netCDF-4 file, it is not really necessary.

If we refrain from using netCDF-4 user-defined types, hierarchical groups, and unsigned integer types (and this is the current plan, AFAIK), then the output files will continue to be readable by netCDF classic code. The NC4_CLASSIC_MODEL flag is not needed for this, we will still get it.

Eliminating the initialsize and chunksize optional parameters is good. They are ignored for NC_NETCDF4 files. NetCDF-4 chunksizes are set on a per-variable basis, when the variable is defined. If you don't explicitly set the variable chunksizes, then netCDF will take a guess and come up with chunksizes for each var.

So this is a good change.
