  COMMAND WATERZFRAME
-----------------------------------------------------------------
    Purpose: create single object of a realistic water-wave,
             but change only the z-coordinates of the objects 
             (isn't as realistic as WATERFRAME)
      Usage: WATERZFRAME(<objectID>,<frames>,<frame>,<destID>,
                         [<amplitude>,<wavelength>,<sourceX>,<sourceY>,
                         <damping>,<times>,<rings>])
   Examples: waterzframe(1,40,20,2,12.0,24,10,-10,1.6,4,2)
             waterzframe(1,60,33,4)
