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

Speed ups and simplifications of the free rotor pseudo-ellipse 2nd degree frame order matrix equations.

Implemented the compile_1st_matrix_pseudo_ellipse_free_rotor() function.

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

Created the Grace graphs for the free rotor 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.

Small numerical changes for the pseudo-ellipse 2nd degree frame order matrix graphs.

These are only for the first point close to zero and the changes are minimal, caused by the recent
simplifications of the code.

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.
