    *
    * Magazine articles written by Tim Tillson
    *
    * Essentially, a T3 of time serie 't' is:
    *   EMA1(x,Period) = EMA(x,Period)
    *   EMA2(x,Period) = EMA(EMA1(x,Period),Period)
    *   GD(x,Period,vFactor) = (EMA1(x,Period)*(1+vFactor)) - (EMA2(x,Period)*vFactor)
    *   T3 = GD (GD ( GD(t, Period, vFactor), Period, vFactor), Period, vFactor);
    *
    * T3 offers a moving average with less lags then the
    * traditional EMA.
    *
    * Do not confuse a T3 with EMA3. Both are called "Triple EMA"
    * in the litterature.
