##Current Bugs
- FeatureGen outputs a BS row in the first line (see repeated hour value)
##Latest Fixes
- Hours that contain no tweets have appropriate value for time of day (24hr)
- Added functionality to create train/test set via list of indices
##Todo
- Add new features for Part 3 in Feature.py
- Clean up TweetStats.py modules (separate FeatureGen and Part 1 stats)
- Prune DataFrame based on time window (for Part 4) e.g date < Feb 1st
- Fix the feature building (Tweet count should be for next hour)
