* This script removes previous tasks from disk to clear space.
* Configure the date on lines 22-23 to change the dates after/before which
* to delete.
* This works based on sessions dates (it will not delete tasks from
* base courses).
* Configure the date on line 22 to change the date before which to delete,
* then delete the exit() statement at line 13.
* This works based on sessions dates.
* This script should be located inside the tests/scripts/ folder to work
