- Initial implementation of analysis.
- Download and unzip raw data set.
- Ignore RStudio project files.
- A lot of progress towards creating a tidy data set. Still need to
  save the output to a file..
- Update .gitignore to ignore the data directory. Don't include
  raw and processed data in the repository.
- Update the README.md file describing the repository.
- Modifications to the analysis script to be more verbose, to place
  the data within the current working directory, and to generate
  a tidy dataset.
