Since we're going to be workshopping database ideas, we need a good way to reset the database and easily mock up some new data.

• Delete current sqlite database by either calling python manage.py flush or simply deleting the db file.
• Modify the hospital/management/commands/create_db.py command to create new instances/relations.
• Call custom management command via python manage.py create_db. This will make the migrations and populate the db.
• Use python manage.py shell_plus to enter interactive shell to verify.

This assumes Ubuntu May need alternate steps for windows/mac
