Basic scraping and processing to show professor contact info

This does not take in to account names like "Eddie Dupont" which we currently won't match. A future PR will implement a feature to make the connection between Eddie and Edward. Also note this only shows the info on the prof page, and not the course pages they may be mentioned on. Though that could be added to this PR if you guys want.

nit: `required=False` is the default behaviour, so you don't need to specify it.
