+/// HttpResponse is instantiated by the library and handed to
+/// the caller during callbacks to the handler.  It supplies
+/// all the status, header and HTTP body data the caller is
+/// interested in.  Methods provide simple getters to return
+/// individual pieces of the response.
+///
+/// Typical usage will have the caller interrogate the object
+/// and return from the handler callback.  Instances are refcounted
+/// and callers can bump the count and retain the object as needed.
+///
+/// Threading:  Not intrinsically thread-safe.
+///
+/// Allocation:  Refcounted, heap only.  Caller of the constructor
+/// is given a refcount.
