CDAT creates NetCDF4 files when it should create NetCDF4-classic files

[stephenpascoe]

I believe Cdunif does not support NetCDF4-model features (e.g. unsigned types, groups, structures). If so I would expect it to create NetCDF4-classic files by setting the NC_CLASSIC_MODEL flag when calling nccreate(). Instead it creates a full NetCDF4 file by setting the NC_NETCDF4 flag.

This has confused at least one user who expected to be able to create unsigned integer types using cdms2.

Note the code ref is Packages/cdms2/Src/Cdunifmodule.c:1162

You're right that is probably a good idea.I'll look into it. Also since I'll be tweaking this code. Should we revert the default behaviour to be NetCDF3 files?

should be fixed in devel branch bug406_cdms2NC4_files_not_classic
