 * List of {@link Flag} objects for use in SystemUI.

 * Flag Ids are integers.
 * Ids must be unique. This is enforced in a unit test.
 * Ids need not be sequential. Flags can "claim" a chunk of ids for flags in related features with
 * a comment. This is purely for organizational purposes.

 * On public release builds, flags will always return their default value. There is no way to
 * change their value on release builds.
