coffee.n-u tastes.v the same

@ruiting I was thinking that DD connector is also used to connect determiners to adjectives when they
are being used as self-contained noun-phrases. In this case "the same" as a object. another example is "It applies to the poor" I got this idea from here http://www.abisource.com/projects/link-grammar/dict/section-DD.html (see last two paragraphs)
