* Asynchronous operations may represent a continuation of the asynchronous

* Implement asio_handler_is_continuation for your own handlers to indicate
* when a handler represents a continuation.

* The default implementation of the continuation hook returns <tt>false</tt>.

* @code
* class my_handler;
*
* bool asio_handler_is_continuation(my_handler* context)
