Added a new property to TCustomTeeFunction:

ValueIndex : Integer

(Default value is -1, meaning it has no valid value).

At function OnCalculateEvent, ValueIndex goes from 0 to NumPoints-1

procedure TForm1.TeeFunction1Calculate(Sender: TCustomTeeFunction;
  const x: Double; var y: Double);
begin
  y:=x+TeeFunction1.ValueIndex;
end;
