This uses the CaM frame order synthetic data for the rotor model to visualise the pseudo-ellipse
frame order model axis permutations. The initial conversion sets the pseudo-ellipse torsion angle
cone_sigma_max to the rotor opening half-angle, and the pseudo-elliptic cone opening to close to
zero. Then the axis permutations are performed. All three solutions are optimised. PDB
representations before and after optimisation are included to illustrate any problems.
