+//! This class largely exists to emit events for the OutlinerWidget to listen in on.
+//! The logic for these events is best off not happening within the tree itself,
+//! so it can be re-used in other interfaces.
+//! The OutlinerWidget's need for these events is largely based on the concept of
+//! delaying the Editor selection from updating with mouse interaction to
+//! allow for dragging and dropping of entities from the outliner into the property editor
+//! of other entities. If the selection updates instantly, this would never be possible.
