Add ntriple/turtle parser

User rubens N3 parser. Should still be pretty small, so it shouldnt impact the library size that much.

Using this parser, we can show construct/describe results in tables as well (just 3 columns)

Just cleaning up old issues. Don't want another dependency that increases the lib size,with little added benefit
