code: @Deprecated
      public static <T> CombinableEitherMatcher<T> either(Matcher<? super T> matcher) {
          return CoreMatchers.either(matcher);
      }
docs: This is useful for fluently combining matchers where either may pass, for example:
  <pre>
  assertThat(string, either(containsString("a")).or(containsString("b")));
  </pre>
  
  @deprecated Please use {@link CoreMatchers#either(Matcher)} instead.
