Updating data

All of the data probably needs to be reviewed once a year to see if it needs to be updated

Process:

1. checkout current master branch
2. Go through each source
   1. Find website data came from
   2. Look if there is a new version of data
   3. Download new data, open it in QGIS to make sure it looks right
   4. If there is a newer version of the data decide if it becomes a new source, or the current source gets updated. In most cases the right thing to do is to make a new source, and if the old source doesn't have a year in the name, add a year. To make a new source duplicated the existing file, and the put the year for the new data in the name.
   5. Modify the json file to point at the new data url, and adjust field mapping if necesary

Updates could be done with 1 change per branch, but it's probably easiest to do 1 branch and pull request per state.
