/* Note from Andrew on Jan. 22, 2017: This class is a design problem for me, so I left it with an
* awkward name. TimelineFragment and NotificationFragment have significant overlap but the nature
* of that is complicated by how they're coupled with Status and Notification and the corresponding
* adapters. I feel like the profile pages and thread viewer, which I haven't made yet, will also
* overlap functionality. So, I'm momentarily leaving it and hopefully working on those will clear
* up what needs to be where. */
