Simplification of some of the pseudo-ellipse 2nd degree frame order matrix equations.

Alphabetical ordering of methods in the frame order matrix element simulation script.

Simplifications for the inside_*() methods of the frame order matrix element simulation script.

The limit() method is now called only once outside of these methods and the maximum cone half-angles
passed into the inside_*() methods. Although only slightly faster, this is mainly to simplify the
code.

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

The generated in-frame and out-of-frame Grace graphs for the torsion angle cone_sigma_max,
containing the matrix values for 1,000,000 simulation values have been added to the repository. The
inside_iso_cone() method has been created to check for the theta_x and theta_z angle violations from
the rotation_hypersphere() method.

Created the Grace graphs for the torsionless pseudo-ellipse model 1st degree frame order matrix.

These are the values calculated directly from the lib.frame_order modules. The graphs were
previously all zeros.

Implemented the compile_1st_matrix_pseudo_ellipse_torsionless() function.

This is for the lib.frame_order.pseudo_ellipse_torsionless module. The function will calculate the
1st degree in-frame frame order matrix for the torsionless pseudo-ellipse model.

Simplifications for all of the torsionless pseudo-ellipse frame order matrix equations.

Updated all the calculated 1st degree frame order matrix graphs for the pseudo-ellipse.

The changes are due to the fixes in the lib.frame_order.pseudo_ellipse module.

Simplifications and fixes for the 1st degree frame order matrix calculation for the pseudo-ellipse.

The compile_1st_matrix_pseudo_ellipse() function of the lib.frame_order.pseudo_ellipse module has
been significantly simplified by shifting a lot of maths outside of the quadratic integration.

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

The generated in-frame and out-of-frame Grace graphs containing the matrix values for 1,000,000
simulation values have been added to the repository. The inside_free_rotor() method has been added
to always return True for the rotation generated by rotation_z_axis().
