com.hp.hpl.jena.reasoner.rulesys.Node_RuleVariable
A variation on the normal Node_Variable which support for value bindings. Currently the forward rule system stores the values externally but requires variables to have an offset index in the rule environment vector. The variables can also suport prolog-like reference chains and trails but these are not yet used.
Note that this should not be used in a real Triple, in particular it should not end up in a Graph. It is only needed for the rule systems.

            trailValues = new Node[trailLen];
            trailVars = new Node_RuleVariable[trailLen];
        }
        trailLength = trailLen;
        for (int i = 0; i < trailLen; i++) {
            Node_RuleVariable var = (Node_RuleVariable) trail.get(i);
            trailVars[i] = var;
            trailValues[i] = var.getRawBoundValue();
        }
        // Save the permanent variables
        Node[] currentPVars = envFrame.pVars;
        if (currentPVars != null) {
            if (pVars == null || pVars.length < currentPVars.length) {
