#Usage
#Initiate a new instance of an OurVleBrowser
browser = OurVleBrowser()

sas.py
Logs in to a student's SAS account and gets their schedule, then parses the relevant information using regex, because 
SAS's HTML is too ugly to use a parser.
Todo:
(!) Refactor times returned by the parser to datetime objects to allow for easy time-related operations.
    Or not, because it's just a prototype, and that's a lot of effort for a proof-of-concept
