# PROBLEM: This implementation is bad due to inconsistencies in the website
|
|
# The way we can tell the difference between an assignment and an exercise is by the presence of an a with the class "ass-submitable"
|
|
# As opposed to folders which contain exercises which are marked with "ass-group"
|
|
# Therefore, we should take that into consideration and spawn the corresponding Exercise or Assignment class
|
|
# Naming becomes a bit inconsistent like that as well, as Assignments could be Exercises. Might opt to call the "assignments" "exerciseGroups" or some shit.
