+* Description:  The MCoreDbSyncRecoveryHandler provides means to restore the database
+*                synchronisation between Speech Recognition DB (SR DB) and VAS DB.
+*
+*                Training a new name saves stuff to SR DB. The SaveTag() call saves
+*                stuff to VAS DB. If the client decides after training not to save, or
+*                battery is removed between training the name and saving it, then the
+*                two databases are out of sync.
+*                These functions add to VAS DB enough information for proper rollback.
+*                If they are called before changing SR DB, the databases will always
+*                stay in sync.
