Fixes for the torsionless pseudo-ellipse 1st degree frame order matrix element graphs.

Bug fix for the torsionless pseudo-ellipse 1st degree frame order matrix.

The 11 element was of the wrong sign.

Added the torsionless pseudo-ellipse model to the frame order matrix element simulation script.

The generated Grace graphs containing the matrix values for 1,000,000 simulation values have been
added to the repository. The rotations are generated by the rotation_hypersphere_torsionless()
method and the angle violations checked using the inside_pseudo_ellipse() method.

Added the free rotor isotropic cone model to the frame order matrix element simulation script.

The generated Grace graphs containing the matrix values for 1,000,000 simulation values have been
added to the repository. The self.torsion_check variable has been created to allow the
inside_iso_cone() method to skip the torsion angle check when its value is False.

Created and added all of the torsionless isotropic cone simulated frame order matrix element graphs.

Added the isotropic cone model frame order matrix simulation graphs for the cone opening angle theta_x.

Changed the frame_order.quad_int user function argument default to True.

This means that calling the user function without arguments will activate the quadratic integration
rather than turning it off.

The frame order auto-analysis summary functions are now more robust.

If the data pipe already exists for some reason, it is deleted prior to the new one being created.

Bug fix for the activation of quadratic integration in the frame order auto-analysis.

The calls to the frame_order.quad_int user function in the optimisation() method did not supply an
argument so the user function was defaulting to False rather than the True value required.

A few Frame_order system test updates for the float64 to float32 memory saving changes.

The chi-squared value of 3 tests was slightly different.
