Checks whether the given {@link Request} object matches this matcher.
@param o {@link Request} object to be matched by this matcher. If this param is not of type {@link Request} this
method will always return {@code false}.
@return {@code true} if the value retrieved using {@link #retrieveValue(net.jadler.Request)} from the given
{@link Request} object matches the predicate registered by the {@link #RequestMatcher(org.hamcrest.Matcher)},
otherwise {@code false}.
