Making this the data repository

I think we should make this the repository that only deals with data. It's been that for a long time. This pull request deletes the files that are not related to the data we use for the FOIA modernization project. These get added to the foia-general repository as we do not want to delete them permanently. 
Github did the diff here poorly. We are replacing the repository's README with the read me file in contacts/ as it's more relevant.
