/**
* Junit test for {@link RelTagParser} based mainly John Xing's parser tests.
* We are not concerned with actual parse text within the sample file, instead
* we assert that the rel-tags we expect are found in the WebPage metadata.
* To check the parser is working as expected we unwrap the ByteBuffer obtained
* from metadata, the same type as * we use in expected (String). So just the
* other way around as we wrapped the metadata value.
