Only add specified assignments/files

[betatim]

Right now abc-author adds all assignments to the student directory. Similarly abc-distribute will generate a PR that modifies everything.

Instead we want to have abc-author assignment1 which only adds assignment1 related files to the already existing student/ directory. abc-author -d assignment1 would remove the assignment from the student/ directory again.

abc-distribute (w/o arguments) would generate a PR based on everything in student/ (copy over whole student/ directory). abc-distribute assignment1 would only create a PR with changes for that assignment (copy over only the assignment specific sub-directory from student/).

One thing that will be tricky to figure out is the .circleci/config.yaml which we will need to edit as we do this.

I had another thought about this yesterday @betatim Right now what works well is each time i distribute content we reset the PR in the student's directory. This handles the student that maybe misses the first assignment for whatever reason or any assignment. Is there a clever way to still ensure that we don't get PR merge conflicts for the students?

related to this issue as well.
And this one too.

closing this for the time being as we are using nbgrader now!
