Detailed Description

---

CoordinateTransform transforms between the coordinate system centred
at the entrance and the local Frenet-Serret coordinate system. Assuming
CoordinateTransform takes in the fringe field parameters and calculates
the coordinate transformation. First the coordinates are transformed to
a coordinate system centred in the middle of the magnet. From here
the Frenet-Serret coordinates are found using numerical integration.
