• Adds named parameter getters (as complement to integral offset getters) like so:

	/* Define a parameter route */
	.get("/:first/static/:second", [](auto *res, auto *req) {

		/* Use the value of a parameter as response */
		res->write("<h1>first is: ");
		res->write(req->getParameter("first"));
		res->write("</h1>");

		res->write("<h1>second is: ");
		res->write(req->getParameter("second"));
		res->end("</h1>");

	})

• Adds new example showing the above in use.
