The netCDF export module can only save a subset of all possible VisAD
data objects. One of the objects it can't save is a FieldImpl with a
Irregular1DSet domain. The reason for this is because the coordinate
variables in a netCDF dataset should be sorted.
I'm going to modify the code so that Plain.save(String) throws a
BadFormException in this case.
In any case, you should modify your code so that the FieldImpl has a
Gridded1DSet for the domain.
