I added code here to read the config file, and find it from anywhere in a box course.
modified how the config file is read here. I am not sure this works now as a standalone module. at the moment I only use this module in box-course, but it could be useful as a standalone module too.
lots of new changes. I added a course json file that stores all data from a central place. I updated create, assign to use that new file, and update it. Assign now requires categories, points and duedates. added a config command.
