Detailed Description

   template<typename _Ch_type, typename _Rx_traits = regex_traits<_Ch_type>>
       class std::basic_regex< _Ch_type, _Rx_traits >" Objects of specializations of this class
       represent regular expressions constructed from sequences of character type _Ch_type.

       Storage for the regular expression is allocated and deallocated as necessary by the member
       functions of this class.
