This pull request deals with much of the back-end. The system calculates how many users are logged in at once, and it creates a cue that prioritizes Minerva students and who arrived first. It adds new functionalities such as a proper timer and automatically redirecting a user to the main room, limiting one person in the main room at all times, and limiting your time in the main room to five minutes after which you will be redirected back to the observe room. Moreover, I created a secret control room that looks over all the users and can be used to keep track of the users or for testing purposes
