Simplifications of pseudo-ellipse 1st degree frame order matrix functions.

The xx, yy, and zz have been renamed to 00, 11, and 22 for consistency. And all sigma_max arguments
have been dropped as they are not used.

Removal of many repetitive calculations in the pseudo-ellipse 2nd degree frame order matrix equations.

Integer to float conversions in part_int_daeg2_pseudo_ellipse_13().

This avoid integer to float conversion during execution, saving a little time for the pseudo-ellipse
2nd degree frame order matrix compilation.

More simplifications of the pseudo-ellipse 2nd degree frame order matrix equations.

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.
