EMA Enveloper Indicator & a crazy prediction

EMAEnvelope indicator does just that, draws a nice user-defined period EMA envelope (overlay).

It also can highlight the Bull/Bear breaks using different colors
- Green : High > EMA_HIGH
- Lime : (High > EMA_HIGH) and (Low > EMA_HIGH)
- Orange : Low < EMA_LOW
- Red : (Low < EMA_LOW) and (High < EMA_LOW)

Background highlighting is user-configurable.

Now to the (crazy) prediction: Based on a 100-period EMAEnvelope, we may have to go down to ~427.3 before starting turning Green. Look at the 2 Orange/Red areas highlighted.

EMA 200 tells us a different story, BTW.
