/*                     HARMONIC PATTERN DETECTION

Automatic Detection of Harmonic Patterns - Gartley, Bat, Butterfly and Crab.

Zig Zag is not used in this AFL. It is based on fractals

Contact - [email protected]

Modernized by E.M.Pottasch (Dec 2016).
- All calculations by the original author left as they were.
- Improved visualisation of the patterns.
- Adjusted names of variables, constants and arrays, adapted
	using code from David Keleher.

The code I used is the original code from:
