<P> A time series smoothing operator. For two values with the given <I>Distance</I>, 
  the first one is multiplied with <I>TailWeight</I> and the second one with <I>HeadWeight</I>. 
  The resulting average is written into <I>OutputValueBA</I> and becomes the new 
  tail value. <I>HeadWeight</I> and <I>TailWeight</I> must sum to 1.<BR>
