Add tests for an assignments feed method
Add an assignments method to users
Make the intent of assignment ordering test more clear
Make displaying all assignments for a course slightly more pretty
Use current_user? instead of a comparison
Move the "Add assignment" button to its own partial, format it a bit
Move display for a single assignment in a list into a shared partial
Add tests to assure that we display a course's assignments
Add tests for showing the current user's assignments on the root_path
Show the current user's assignments when signed in on the root path
Add another assignment to the user#assignments test
Remove redundant test
Add tests for option to strictly return open assignments
Add an only_open option to user#assignments

This implementation stinks. I need to fix it.
Use Ruby instead of SQL to find open assignments

This makes sure of DRY when defining what "open" means in the context
of an assignment.
