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.

This will not work if the profs directory does not exist. You need to either add code that creates the directory first if it does not exist, or you need to add the directory to the repo.

Note that git will not add empty directories, so you need to to add a placeholder file to the directory (our convention is to add a file called `.gitkeep`).
