types and functions for XABCD pattern detection and plotting

method set_tolerances(this, tolerance_Bmin, tolerance_Bmax, tolerance_Cmin, tolerance_Cmax, tolerance_Dmin, tolerance_Dmax)
  sets tolerances for B, C and D retracements. This creates another Pattern instance that is set as tolerances field on the original and will be used for detection instead of the original ratios.
  Namespace types: Pattern

mute this pattern by making it all one color (lines and labels, for pattern fill there's another)
  Namespace types: Match

method mute(this, mute_color, mute_fill_color)
mute all patterns in this map by making it all one color (lines and labels, for pattern fill there's another)

draw this Match on the chart
  Namespace types: Match

method draw(this, config, all_patterns, debug_log)
draw all Matches in this map, considering all other patterns for engulfing and overlapping
  Namespace types: map<string, Match>

method check_hide_or_mute(this, all, config, debug_log)
checks if this pattern needs to be hidden or muted based on other plotted patterns and given configuration
  Namespace types: Match

method add_if(id, item, condition)
convenience function to add a search pattern to a list, only if given condition (input.bool) is true
  Namespace types: Pattern

Pattern
  type to hold retracement ratios and tolerances for this pattern, as well as targets for trades

Config
  allows control of pattern plotting shape and colors, as well as settings for hiding overlapped patterns etc.

Match
  holds all information on a Pattern and a successful match in the chart. Includes XABCD pivot points as well as all Line and Label objects to draw it
