In HamletTagger.java, Reduce class is not used at all #3

In HamletTagger.java, Reduce class is not used at all. IdentityTableReducer is used instead. Since Reduce.reduce() is somewhat special by Put()ing only the first record, it cannot be replaced by IdentityTableReducer, at least for performance.
