Bugs:
no_submissionscount is wrong. It seems to substract the total submissions from the amount of students/projects in a course. In the case that a teacher submits an assignment (which (s)he obviously shouldn't do, but it's possible) the count is wrong.on_time=true||falseboth don't return any submissions.
Features:
The ability to query users/projects that have not submitted the assignment yet with no_submission=true||false query parameter.
