This package provides Python bindings for libwignernj, a C99 library
designed for the exact evaluation of various angular-momentum coefficients
(Wigner 3j, 6j, and 9j symbols, Clebsch-Gordan coefficients, Racah
W-coefficients, Fano X-coefficients, and Gaunt coefficients) used in
atomic, molecular, nuclear, and electromagnetic-scattering applications.
