represents a node in dot lang. #Example:

    fn node_test() {
        use dot_generator::*;
        use dot_structures::*;

        assert_eq!(node!(), Node::new(NodeId(id!(), None), vec![]));
        assert_eq!(node!(html "abc"; attr!("a","a")),
                   Node::new(NodeId(id!(html "abc"), None),
                             vec![attr!("a","a")]));
        assert_eq!(node!(html "abc" ; attr!("a","a")),
                   Node::new(NodeId(id!(html "abc"), None),
                             vec![attr!("a","a")]));
        assert_eq!(node!("abc" ; attr!("a","a"),attr!("a","a")),
