added blank README file
minor changes to SentimentAnalysis (sorted results) and added TODO.txt
Same files, though this time with retrained classifiers. Using only ngram features, each classifier trained for 10 iterations. this gave the following accuracies: top = 0.903, bottom = 0.904, all = 0.946. The MRR scores for this were all = 0.745, bottom = 0.686, top = 0.6865. It looks like we aren't computing MRR with merged though, at the moment... look for that in the next commit
