FloatSets are inappropriate as Field domains since FloatSet
has nearly 2**32 members (all legal 32-bit floating point bit
patterns). They are only really used as range sets of FlatFields,
where they always have domain dimension = 1. Thus the MathType
passed to FloatSet is (always in practice) the RealType of a
FlatField range component. In fact, you don't even have to do
that, since FloatSet is the default range set for FlatField
range components, so FlatField constructs them implicitly.
Bottom line, you rarely have to do anything with FloatSets.
For example, 'grep FloatSet *.java' in the visad/examples
directory doesn't find any matches.

Well, we'd really love to add your HDF5 file adapter code
to the VisAD source distribution, and make a link to it a
permanent part of DefaultFamily.
