public class FilteredClassifier
Class for running an arbitrary classifier on data that has been passed through an arbitrary filter.
Valid options from the command line are:
-W classifierstring
Classifierstring should contain the full class name of a classifier
(options are specified after a --).
-F filterstring
Filterstring should contain the full class name of a filter
followed by options to the filter.
