Right now, when students are flagged by a sufficient number of other students as being in a room incorrectly, they are shown with an asterisk.

Instead, I like the design paradigm where flagged content is separated out and hidden by default, with users given the opportunity to click a button to see it if they wish.

Modify the queryset in the view for the floor and room pages to separate out flagged students, and then modify the template to hide flagged students behind a collapsing div. https://getbootstrap.com/javascript/#collapse
