* Implements the IPPROTO_IPV6/IP_V6ONLY socket option.
*
* @par Examples
* Setting the option:
* @code
* boost::asio::ip::tcp::socket socket(io_service);
* ...
* boost::asio::ip::v6_only option(true);
* socket.set_option(option);
* @endcode
*
* @par
* Getting the current option value:
* @code
* boost::asio::ip::tcp::socket socket(io_service);
* ...
* boost::asio::ip::v6_only option;
* socket.get_option(option);
* bool v6_only = option.value();
* @endcode

* @par Concepts:
* GettableSocketOption, SettableSocketOption.
