*
* Accepts a string to search, a left and right format delimiter
* as regex patterns, and optional regex flags. Returns an array
* of matches, allowing nested instances of left/right delimiters.
* Use the "g" flag to return all matches, otherwise only the
* first is returned. Be careful to ensure that the left and
* right format delimiters produce mutually exclusive matches.
* Backreferences are not supported within the right delimiter
* due to how it is internally combined with the left delimiter.
* When matching strings whose format delimiters are unbalanced
* to the left or right, the output is intentionally as a
* conventional regex library with recursion support would
* produce, e.g. "<<x>" and "<x>>" both produce ["x"] when using
* "<" and ">" as the delimiters (both strings contain a single,
* balanced instance of "<x>").
*
* examples:
* matchRecursiveRegExp("test", "\\(", "\\)")
* returns: []
* matchRecursiveRegExp("<t<<e>><s>>t<>", "<", ">", "g")
* returns: ["t<<e>><s>", ""]
* matchRecursiveRegExp("<div id=\"x\">test</div>", "<div\\b[^>]*>", "</div>", "gi")
