Import lectures and grades from university website

[ExalFabu]

Add a way to import everything needed from Unipa.
I've thought of a couple of ways

1. Ugly version: Go to the Unipa website and copy all the text containing lectures info. (with some kind of tutorial explaining how to do it)
2. Very much better version: Log in into Unipa SSO and requesting the data automatically.

2 has still to be figured out, since I don't really know much about CAS Authentication.
Found this that might be useful but doesn't seem a very safe approach. Maybe there is no alternative. Maybe i need to ask S.I.A. (Unipa's IT Office)

Update

Since the whole authentication thing is kind of overkill, the most efficient way is to just be able to extract the data from a single webpage that contains all the information. Basically scraping a link that the user can input.

Pros

• Ease of use
• Gets new users ready to play with the websites

Cons

• Might be hard to scrape the page in less than 10 seconds (Vercel's time constraint for serverless functions on the free plan)
• Ties the website with the University of Palermo website (in the future it might be possible to differentiate the scraping based on the university's URL, allowing PRs to implement these)
