  //
  //  Purpose:
  //    Maintains information about lineouts, including the plot and window that
  //    originated the query, and the window where query results (curve plots)
  //    are drawn.   Keeps a list of ViewerQueries (lineouts) associated with the 
  //    originating plot.

  //    Programmer: Kathleen Bonnell
  //    Creation:   March 5, 2003

  //  Modifications:
  //    Kathleen Bonnell, Fri Mar  7 16:27:04 PST 2003
  //    Removed unnecessary method 'DeleteResultsWindow'.
  //
  //    Kathleen Bonnell, Wed Jul  9 09:21:22 PDT 2003  
  //    Added method ViewDimChanged.
  //
  //    Kathleen Bonnell, Thu Mar 11 08:19:10 PST 2004 
  //    Removed unused GetMaxQueryWidth, GetMaxQueryHeight. 
  //
  //    Kathleen Bonnell, Thu Feb  3 16:27:10 PST 2005 
  //    Added SetLineoutsFollowTime, SetTimeSlider.
