New Additions

Added classes for Sentence, Predicate, Subject, Noun, Verb. Udated GUI
to use listener to parse string into words, then try to classify the
words by matching them to the xml lists. The output from the Listener is
passed back to the IO where it is displayed in the three columns words,
nouns, verbs. Have not had a chance to debug the classification of the
words. Operation does not classify correctly I don't think. Need to look
at whats actually in the xml lists. Removed xml lists from everywhere
except the debug directory.
