Cute Leaflet Map

If we end up building something that captures a users schedule, then it's no extra work to also map out there schedule in a Leaflet instance.

We could even end up making our own map tiles @hawkins for the campus.
Just thoughts. Have your own little bully walk and such.

The issue names no files, tests, or entry points. First inspect how the extension currently captures or displays a user's schedule and verify whether a Leaflet map is in scope. The issue has no concrete completion criteria for the map, campus tiles, or walking routes, so those requirements need to be clarified before implementation.
