Engulfing Candlesticks

This is my personal Pine Script for Engulfing Candlesticks. Plenty of options, solid code, Simple and it works.

**DOES NOT Show same color candlestick engulfing! In other words it will not show a Bullish engulfing a bullish candlestick, or a bearish engulfing a bearish candlestick, like other pine scripts I have found do. Mine doesn't do this!
