 /* The HistoryBackend consists of a number of components:
 
     HistoryDatabase (stores past 3 months of history)
       URLDatabase (stores a list of URLs)
       DownloadDatabase (stores a list of downloads)
       VisitDatabase (stores a list of visits for the URLs)
       VisitSegmentDatabase (stores groups of URLs for the most visited view).
 
     ArchivedDatabase (stores history older than 3 months)
