Even better might be to let FieldsDictionary be an instance of
collections.defaultdict(list) [[assuming Python 2.5 is in use]], in
which case the simpler
FieldsDictionary[key].append(FieldClass(*line.split(",")))
will Just Work. setdefault was a valiant attempt at fixing this
problem, but defaultdict is better.
