Some breaking changes to the API from the previous release. While no new functionality has been added it is more of a refactor to improve future enhancements:
- Splitting up of classes into more distinct units
- `Cmd` and `S3` are now `S3` (for AWS S3 functionality), `Database` for basic DBAPI class interface, and `Redshift` for Load/Unload capabilities which inherits from `S3` and `Database`.
- Clean up of some of the docs, Exceptions, and testing also.
