 * Test the status / completion combinations on an infolog entry

 * Some statuses changes will also change the percent completed value.
 * For example, closed statuses will set completed to 100%, subsequently changing
 * to an open status will change completed to less than 100%.  Changing to new
 * (not-started) will set completion to 0%.
 *
 * The list of status and percentage changes is stored in a JSON file
