Class that generates weights and abscissas for Gauss-Jacobi quadrature. The
weights $w_i$ are given by:
$$
\begin{align*}
w_i = \frac{2^{\alpha + \beta}(2n + \alpha + \beta)\Gamma(\alpha + n)\Gamma(\beta + n)}{n!\Gamma(n + \alpha + \beta + 1)J_i'(x_i) J_{i - 1}}
\end{align*}
$$
where $x_i$ is the $i^{th}$ root of the orthogonal polynomial, $J_i$ is the
$i^{th}$ polynomial and $J_i'$ is the first derivative of the $i^{th}$
polynomial. The orthogonal polynomial is generated by
JacobiPolynomialFunction.
