Changing the status of the assignment for the Meetup:
Not started - the user did not open the tasks after assignment;
Started - a task can only change from "not started" to "started" if the user has opened the task at least once. The status will change even if the user has opened the task before the date of the Meetup.
Completed - A meetup becomes 'completed' if the tutor gives a mark to the user. The grade must be higher than the completion threshold specified in the task. The status of the task will also change if the user sets a self-esteem (provided the assignment has a "Self-esteem" setting)
Failed - A meetup goes to 'failed' status if the tutor gives a grade for the user which is less than the completion threshold. The same is true for the self-esteem.
