//       Class : NodeVertexTransform
// Description : This VertexTransform gets its matrix from the
//               Transform stored on a node.  It can also compose its
//               node's transform with another VertexTransform,
//               allowing you to build up a chain of
//               NodeVertexTransforms that represent a list of
//               composed matrices.
