    This script will let you easily undone migrations, removing migration files, re-migrate and createsuperuser. 
    It's cumbursome to do this all the time by hand. Well, normally you wouldn't need to do this very frequently, 
    but for beginners like me, it is convinient to have a script to automate this.
