It depends on the filename; specifying "foo.nc" saves the file in netCDF
format, "foo.vad" saves in VisAD format, etc.

However, only FITS, HDF5, netCDF, and VisAD have save() methods, so
"foo.gif" will end up saved in FITS format (since that's the first
method on DefaultFamily's list.)  I suppose this should be a bit
more intelligent...

Right now, FITS, GIF/JPG/PNG, HDF-EOS, netCDF, Vis5D, VisAD,
McIDAS AREA and HDF5 are supported.

If those aren't enough for you, adding new a data type to DefaultFamily
is easy (once you've done the "trivial" work of writing a VisAD file
adaptor :-)
