Title: Submission: Sentiment Analysis over Tweets

My submission to the UDx contest - simple sentiment analysis over tweets. Allows the user to perform Twitter searches from the database, and run simple sentiment analysis over the tweet text to figure out positive/negative sentiments.

examples/demo.sql has an example of how it may be used (finds the average sentiment scores for various US airlines).
