/* MozDownload
   Holds information used to display a single download in the UI. This object is 
   created in one of two ways:
   (1) By nsExternalHelperAppHandler when Gecko encounters a  MIME type which
       it doesn't itself handle. In this case, the notifications sent to
       nsIDownload are controlled by nsExternalHelperAppHandler.
   (2) By the embedding app's file saving code when saving a web page or a link
       target. See CHeaderSniffer.cpp. In this case, the notifications sent to
       nsIDownload are controlled by the implementation of nsIWebBrowserPersist.
