Implement an extra-lecture-planner #4
Description
(Yamini's idea)
The timetable frontend can be extended to help plan extra lectures and quizzes.
Currently, a professor or student can put the timetable creator on the projector and ask students which slots are filled and fill them on the creator. This is pretty useful for finding out which slots are mutually empty in the week, but we can go deeper.
We can create a php backend that lets students submit slot details (there already is a JSON format for it) to a prof, and the prof gets a collated set of slot details all loaded into the timetable so that he can look for mutually free slots.
