Ever wonder how the weights and abscissae are calculated for the numerical conversion from radiance to flux? The long and the short of it is that Gauss-Jacobi quadrature determines the weights and abscissae which is similar to Gaussian for low-point quadrature but differs substantially for high-point quadrature. This program follows Abramowitz and Stegum to produce the roots of a Jacobi polynomial from which both weights and abscissae are determined.

Updated structure and commenting for readability (thanks to user reviews). Also, there was a bug in the determination of the weights that was fixed.
