Manually grading a student's solution

After assignments have been autograded, they will saved into an autograded directory (see the philosophy and the approach for details):

After running nbgrader autograde, the autograded version of the notebooks will be:

autograded/{student_id}/{assignment_id}/{notebook_id}.ipynb

To grade the assignments with an HTML form, all we have to do is run:

nbgrader formgrade

This will launch a server at http://localhost:5000 that will provide you with an interface for hand grading assignments that it finds in the directory listed above. Note that this applies to all assignments as well -- as long as the autograder has been run on the assignment, it will be available for manual grading via the formgrader.

The formgrader doesn't actually modify the files on disk at all; it only modifies information about them in the database. So, there is no "output" step for the formgrader.
