Expand description

A RDF triple without blank nodes.

The default string formatter is returning a N-Quads representation.

use spargebra::term::{GroundTriple, NamedNode};

assert_eq!(
    "<http://example.com/s> <http://example.com/p> <http://example.com/o>",
    GroundTriple {
        subject: NamedNode::new("http://example.com/s")?.into(),
