I am trying to learn how to use the Physics tensor routines by using a simple 2D example.  In the following, I set up the Cartesian Euclidean metric tensor and then tried to transform to cylindrical coordinates.  The metric tensor is correctly transformed in line (5), but then when it is called in line (7), it still has Cartesian values.  What am I doing wrong?
