Subject: Started verbly rewrite

verbly is intended to be a general use natural language generation library. Here, I'm using it to simply generate random verbs or adjectives. A schema for the sqlite database is provided, and for testing I manually added data. A generator program is being written that will generate a database from WordNet, VerbNet, PropBank, and AGID data.
