Integrate with UI

[brianavecchione]

Checkin should have a visualization of entities in-office on a daily basis (flushed daily for those who do not wish to keep their info in CG). All entities should be loaded, but only the entities in-office should be colored on-click.

*Important to note that this visualization/data should not be publicly accessible, for privacy reasons. The UI should have some kind of security implementation (possibly password auth), and the redis data should not have an accessible API.
