Misc Cleanup

Cleaned up the following items:
- Restructured the project layout to keep all data partitioned from our source/scripts
- Dockerized the application (check out the readme for info on running this in docker)
- Removed absolute paths from R scripts (replaced with relative paths)
- Minor formatting tweaks here and there
- Removed some env files from the repo that probably don't need to be there

Take a look and let me know what you think. Thanks!
