In this chapter we are going to create a custom orientation on the curve,
 that will allow us to have the train leaning into a turn and also follow its slope.

We are going to use the super formula to create an interesting shape for the rail itself and finally isolate tunnel segments for further processing.

In this clip we lerp the curve and categorize it into leaning groups.
