/**
     * If this geometry node is deformed by a skeleton, this
     * returns the node containing the skeleton.
     * 
     * In jME3, a mesh can be deformed by a skeleton only if it is 
     * a child of the node containing the skeleton. However, this
     * is not a requirement in FBX, so we have to modify the scene graph
     * of the loaded model to adjust for this.
     * This happens automatically in 
     * {@link #createScene(com.jme3.scene.plugins.fbx.node.FbxNode)}.
     * 
     * @return The model this node would like to be a child of, or null
     * if no preferred parent.
