 * Matcher for concurrent changes of the system/component under test.

 * <dt><strong>Example:</strong></dt>
 * <dd>
 * <pre>{@code Deque<String> strings = new ArrayDeque<>(Arrays.asList("Lorem", "Ipsum"));
 * Probe.<Deque<String>, String>probing(strings)
 *      .withinMs(1L)
 *      .assertThat(
 *                  new Function<Deque<String>, String>() {
 *                    @Override
 *                    public String apply(Deque<String> input) {
 *                      return input.pop().toLowerCase();
 *                    }
 *                  },
 *                  Matchers.equalTo("ipsum")
 *      );
 * }</pre>
 * <p>
 * While this example is somewhat academic you still might get the meaning. While the test above
 * triggers the state change, a typical system of course changes its state over time.
