Description

I tried to execute POSTaggerCrossValidator with the -ngram parameter and it caused a UnsupportedOperationException.

Sometimes it is interesting for some training tools to pre-process the corpus to artifacts before training, for example dictionaries.
CrossValidationPartitioner.TrainingSampleStream should support the reset operation to allow this functionality.

Does anybody know why it does not support resetting?
