Detailed Description

   template<typename _BiIter>
       class std::sub_match< _BiIter >" A sequence of characters matched by a particular marked sub-expression.

       An object of this class is essentially a pair of iterators marking a matched subexpression within a
       regular expression pattern match. Such objects can be converted to and compared with std::basic_string
       objects of a similar base character type as the pattern matched by the regular expression.

       The iterators that make up the pair are the usual half-open interval referencing the actual original
       pattern matched.
