-SystemUI and SystemUIApplication also have methods for putComponent and
-getComponent which were existing systems to get a hold of other parts of
-sysui before Dependency existed. Generally new things should not be added

 Each SystemUI service is expected to be a major part of system ui and the
 goal is to minimize communication between them. So in general they should be
 relatively silo'd.

+ * @see #getActiveNotificationUnfiltered(String) to check if a key exists
+ * @see #getPendingNotificationsIterator() for an iterator over the pending notifications

+/**
+ * The system that constructs the current "notification list", the list of notifications that are
+ * currently being displayed to the user.
+ *
+ * The pipeline proceeds through a series of stages in order to produce the final list (see below).
+ * Each stage exposes hooks and listeners for other code to participate.
+ *
+ * This list differs from the canonical one we receive from system server in a few ways:
+ * - Filtered: Some notifications are filtered out. For example, we filter out notifications whose
+ *   views haven't been inflated yet. We also filter out some notifications if we're on the lock
+ *   screen. To participate, see {@link #addFilter(NotifFilter)}.
+ * - Grouped: Notifications that are part of the same group are clustered together into a single
+ *   GroupEntry. These groups are then transformed in order to remove children or completely split
+ *   them apart. To participate, see {@link #addPromoter(NotifPromoter)}.
+ * - Sorted: All top-level notifications are sorted. To participate, see
+ *   {@link #setSectionsProvider(SectionsProvider)} and {@link #setComparators(List)}
+ *
+ * The exact order of all hooks is as follows:
+ *  0. Collection listeners are fired (see {@link NotifCollection}).
+ *  1. NotifFilters are called on each notification currently in NotifCollection.
+ *  2. Initial grouping is performed (NotificationEntries will have their parents set
+ *     appropriately).
+ *  3. OnBeforeTransformGroupListeners are fired
+ *  4. NotifPromoters are called on each notification with a parent
+ *  5. OnBeforeSortListeners are fired
+ *  6. SectionsProvider is called on each top-level entry in the list
+ *  7. The top-level entries are sorted using the provided NotifComparators (plus some additional
+ *     built-in logic).
+ *  8. OnBeforeRenderListListeners are fired
+ *  9. The list is handed off to the view layer to be rendered.
