   Constructs a new regex_token_iterator:
   1) Default constructor. Constructs the end-of-sequence iterator.
   2-5) First, copies the list of the requested submatch out of the submatches or
   submatch argument into the member list stored in the iterator and constructs the
   member std::regex_iterator by passing a, b, re, and m to its four-argument
   constructor (that constructor performs the initial call to std::regex_search) and
   sets the internal counter of submatches to zero.
     * If, after construction, the member regex_iterator is not an end-of-sequence
       iterator, sets the member pointer to the address of the current std::sub_match.
     * Otherwise (if the member regex_iterator is an end-of-sequence iterator), but the
       value -1 is one of the values in submatches/submatch, turns *this into a suffix
       iterator pointing at the range [a, b) (the entire string is the non-matched
       suffix).
     * Otherwise (if -1 is not in the list of submatches), turns *this into the
       end-of-sequence iterator.
   The behavior is undefined if any value in submatches is less than -1.
   6) Copy constructor: performs member-wise copy (including making a copy of the
   member regex_iterator and the member pointer to current sub_match).
   7-10) The overloads (2-5) are prohibited from being called with a temporary regex
   since otherwise the returned iterator would be immediately invalidated.

Parameters
   a - LegacyBidirectionalIterator to the beginning of the target character
                sequence
   b - LegacyBidirectionalIterator to the end of the target character sequence
   re - regular expression used to search the target character sequence
                the index of the submatch that should be returned. "0" represents the
   submatch - entire match, and "-1" represents the parts that are not matched (e.g,
                the stuff between matches)
                the sequence of submatch indices that should be iterated over within
   submatches - each match, may include the special value -1 for the non-matched
                fragments
   m - flags that govern the behavior of re
