Download all assignments from google classroom (student work window)
/**
HOW TO USE
1. go to assignment submissions (classwork > click assignment > student work)
2. open developer console ( F12 or right click > inspect element > console in top)
3. copy and paste this code, assignments will be downloaded in 5 second intervals
NOTE: CHANGE auth_user IF NECESSARY
if you are signed in to multiple google accounts, you need to select whichever you use for classroom
(ie freeuni account). If that account is the default one, leave at 0. Otherwise, sign in to gmail with that account
and the number will be displayed in url bar (https://mail.google.com/mail/u/$number), enter that
NOTE files will be downloaded to default download location (~/Downloads)
move all zips/rars from there before launching the script, afterwards you can easily select
newly downloaded files and move elsewhere
