Keeping track of students’ hackathon attendance eligibility:
Add can_attend_next flag to student (boolean) that has as default True (anytime a user is created this is made to true)
Changecan_attend_next before every hackathon (need a better definition of the trigger for this, but the verification should be based on rules
Rule: all units of same specialization delivered - change to True (or keep True), otherwise False
