the class ZWaveNodeStageAdvancer method advanceNodeStage.

/**
     * Advances the initialization stage for this node. This method is called
     * after a response is received. We don't necessarily know if the response
     * is to the frame we requested though, so to be sure the initialisation
     * gets all the information it needs, the command class itself gets queried.
     * This method also handles the sending of frames. Since the initialisation
     * phase is a busy one we try and only have one outstanding request. Again
     * though, we can't be sure that a response is aligned with the node
     * advancer request so it is possible that more than one packet can be
     * released at once, but it will constrain things.
