 // ProfileSyncService is the layer between browser subsystems like bookmarks,
 // and the sync backend.  Each subsystem is logically thought of as being
 // a sync datatype.
 //
 // Individual datatypes can, at any point, be in a variety of stages of being
 // "enabled".  Here are some specific terms for concepts used in this class:
 //
 //   'Registered' (feature suppression for a datatype)
 //
 //      When a datatype is registered, the user has the option of syncing it.
