Reviewers

When viewing a review request, Review Board periodically checks to see if there
have been any updates to the review request or any new reviews/replies made. It provides some
details like what type of update was most recently seen and by who.

A project last semester updated this resource to provide more detailed information
about what changed on the review request. The goal of this project is to make use of this to
provide an improved UI for showing those changes in some form.
