// Public Domain Tiny Regular Expressions Library
// Forked from https://github.com/kokke/tiny-regex-c
//
// Supports:
// ---------
// '^' Start anchor, matches start of string
// '$' End anchor, matches end of string
// ---------
// '*' Asterisk, match zero or more (greedy, *? lazy)
// '+' Plus, match one or more (greedy, +? lazy)
// '{m,n}' Quantifier, match min. 'm' and max. 'n' (greedy, {m,n}? lazy)
// '{m}' exactly 'm'
// '{m,}' match min 'm' and max. MAX_QUANT
// '?' Question, match zero or one (greedy, ?? lazy)
// ---------
// '.' Dot, matches any character except newline (\r, \n)
// '[abc]' Character class, match if one of {'a', 'b', 'c'}
// '[^abc]' Inverted class, match if NOT one of {'a', 'b', 'c'}
// '[a-zA-Z]' Character ranges, the character set of the ranges { a-z | A-Z }
// '\s' Whitespace, \t \f \r \n \v and spaces
// '\S' Non-whitespace
// '\w' Alphanumeric, [a-zA-Z0-9_]
// '\W' Non-alphanumeric
// '\d' Digits, [0-9]
// '\D' Non-digits
// '\X' Character itself; X in [^sSwWdD] (e.g. '\\' is '\')
// ---------
