Description : Displays event history data using a Lexis "pencil" object
              for each case history.  The input event history data file
              contains a number of data variables any of which may be
              selected for the three coordinate axes.  Any of the
              remaining variables may be used to "paint" the faces of
              the Lexis pencils with colours according to the value of
              the variable.  Such dependent variables may take integral
              values between 0 and 15 while independent variables may take
              any real values.  There will normally be one variable which
              is an index of the case histories.  The resulting "geometry"
              is displayed in a window together with a set of axes and
              annotation.
