Modified compile_2nd_matrix_pseudo_ellipse() to rotate and return the frame order matrix.

Alphabetical arrangement of the functions in the frame_order_matrix_ops module.

Removed the docstring linewrapping in the frame order maths_fns module.

Added support for the pseudo-elliptic cone model in the frame order user function and specific code.

Clean up of the maths functions in part_int_daeg2_pseudo_ellipse_xy().

Added a debugging print out to test_compile_2nd_matrix_pseudo_ellipse().

Reordering of the part_int_daeg2_pseudo_ellipse_xx() functions.

Removal of the T23 transpose from compile_2nd_matrix_pseudo_ellipse() and an index shift of -1.

The removal of the transpose has changed all of the indices in part_int_daeg2_pseudo_ellipse_xx().
These indices now start at zero for easier debugging.

Created compile_2nd_matrix_pseudo_ellipse() for numerically making the 2nd degree frame order matrix.

A series of part_int_daeg2_pseudo_ellipse_**() supplementary functions have been added for this
numerical approximation. The function is also unit tested.

Fix for the print_frame_order_2nd_degree() fn, sys.stdout overwriting now works.
