/*! \fn template<typename Rule = QHttpServerRouterRule, typename ... Args> bool route(Args && ... args)
This function is just a wrapper to simplify the router API.
This function takes variadic arguments. The last argument is \c a callback (ViewHandler).
The remaining arguments are used to create a new \a Rule (the default is QHttpServerRouterRule).
This is in turn added to the QHttpServerRouter.
\c ViewHandler can only be a lambda. The lambda definition can take two optional special
arguments: \c {const QHttpServerRequest&} and \c {QHttpServerResponder&&}.
These special arguments must be the last in the parameter list.
Examples:
\code
QHttpServer server;
// Valid:
server.route("test", [] (const int page) { return ""; });
server.route("test", [] (const int page, const QHttpServerRequest &request) { return ""; });
server.route("test", [] (QHttpServerResponder &&responder) { return ""; });
// Invalid (compile time error):
server.route("test", [] (const QHttpServerRequest &request, const int page) { return ""; }); // request must be last
server.route("test", [] (QHttpServerRequest &request) { return ""; }); // request must be passed by const reference
server.route("test", [] (QHttpServerResponder &responder) { return ""; }); // responder must be passed by universal reference
\endcode
