- *
- * Mini regex-module inspired by Rob Pike's regex code described in:
- *
- * http://www.cs.princeton.edu/courses/archive/spr09/cos333/beautiful.html
- *
- *
- *
- * Supports:
- * ---------
- * '.' Dot, matches any character
- * '^' Start anchor, matches beginning of string
- * '$' End anchor, matches end of string
- * '*' Asterisk, match zero or more (greedy)
- * '+' Plus, match one or more (greedy)
- * '?' Question, match zero or one (non-greedy)
- * '[abc]' Character class, match if one of {'a', 'b', 'c'}
- * '[^abc]' Inverted class, match if NOT one of {'a', 'b', 'c'} -- NOTE: feature is currently broken!
- * '[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_]
