> The following rule fires only once, although there are several Node objects passing the <INFINITY test, and one of them must have the minimum tentDist. A rule with salience -100 shows this.
> rule relax
>     when
>         $n : Node( $ta : tentDist < Graph.INFINITY )
>         not Node( tentDist < $ta )
>         $e : Edge( nodeA == $n, $nb : nodeB, $cost : cost )
>         $b : Node( this == $nb, $tb : tentDist )
>     then
>         if( $ta + $cost < $tb ){
> 	        modify( $b ){
>     	            setTentDist( $ta + $cost ),
>         	    setParent( $n );
>         	}
>             System.out.println( "new td = " + ($ta + $cost) + " from " + $n.getId() + " to " + $b.getId() );
