Cleaned and reorganized some documentation.
Adding a check to make sure the current working directory is set to the directory where the source code is.  Wish there was a better way to set the CWD besides doing it manually for each session.
Adding a way to source all files in the source directory to bootstrap things outside of simply using the markdown files in the analysis directory.  I guess converting this project into a package is the only way in R to do this right.
Added an argument so that you can easily sample a subset of the competition data instead of retrieving the entire set.  This can make experimenting with new modeling approaches quicker and easier.
