<i>Change Detection</i> tracks changes on websites you otherwise would visit

frequently to see if there is something new. Use cases:

* Teacher says grades will be published "soon", but no one knows what "soon" means and you are tired of reloading.

* You are working with a server and wants to know the result from a request, periodically.

* You are waiting for updates on an Exam, like if something was postponed or updated.

* You want to monitor the Dagger documentation to see when Thermosiphon's explanation improves.
