+ *
+ * @author Tolegen Izbassar (t.izbassar@gmail.com)
+ * @version $Id$
+ * @param <T> Item type. Should be able to return own item
+ * @since 2.0
+ *
+ * @todo #485:30min Right now we can only check that InputStream
+ *  have the same content as other InputStream. This is very
+ *  limited usage. Task is to introduce `HmTextBody` that will
+ *  make available to us to use useful string matchers from
+ *  hamcrest. The usage will be like that:
+ *  ```
+ *  MatcherAssert.assertThat(
+ *  response,
+ *  new HmRsTextBody<>(Matchers.startsWith("<html>"))
+ *  );
+ *  ```
+ *  The default constructor should use `Matcher.containsString`
+ *  as default matcher, which is used for matching string to body.
+ *  Current implementation of `AbstractHmBody` should be converted
+ *  to `HmBytesBody` that will check equality of bytes. We can think
+ *  of improving that class lately.
+ *
+ * @todo #485:30min Right now the describeTo doesn't properly
+ *  show the reason behind mismatch. It should show expected
+ *  bytes and actual bytes for better clarification for
+ *  end user. Also describeMismatchSafely should be implemented.
