Created compile_1st_matrix_pseudo_ellipse() for numerically making the 1st degree frame order matrix.
A number of new supplementary functions have been added for this numerical approximation:
part_int_daeg1_pseudo_ellipse_xx()
part_int_daeg1_pseudo_ellipse_yy()
part_int_daeg1_pseudo_ellipse_zz()
tmax_pseudo_ellipse()
