   These are the available options (they get passed in through
   the StatsDialog constructor).

   STATSDLG_FULLWINDOW
   Makes the list control fill the entire window

   STATSDLG_CONTEXTMENU
   Provides a context menu over the list control.

   STATSDLG_SELECT_COLUMNS
   Allows the user the ability to change the available column set

   STATSDLG_VERTICAL
   The data is displayed with the column headers going vertical rather
   than horizontal.  The user has to be aware of this when writing the
   RefreshData() code.
