* component parts, this class implements relative URL resolution: what address you'd reach by
 * clicking a relative link on a specified page. For example:
 *
 * ```java
 * HttpUrl base = HttpUrl.parse("https://www.youtube.com/user/WatchTheDaily/videos");
 * HttpUrl link = base.resolve("../../watch?v=cbP2N1BQdYc");
 * System.out.println(link);
 * ```
 *
 * which prints:
 *
 * ```
 * https://www.youtube.com/watch?v=cbP2N1BQdYc
