Zero Lag Exponential Moving Average (ZLEMA)

The Zero lag exponential moving average (ZLEMA) indicator was created
by John Ehlers and Ric Way.
As is the case with the Double exponential moving average (DEMA) and
the Triple exponential moving average (TEMA) and as indicated by the
name, the aim is to eliminate the inherent lag associated to all trend
following indicators which average a price over time.
