Script for checking whether an online waterloo course has space.
In order to send emails from a gmail account, an App Password must be created and used here. This can be hosted on free tier AWS t2.micro ec2 instance, using the nohup command to run it forever.
There is a bug / feature in this script, where if there is an open spot, an email will be sent every tick (10 seconds). Didn't care enough to fix it when using.
