[documentation] Answer a question concerning quad rule orders and the Duffy transformation

If you construct simplex quadrature rules by tensor multiplication and the
Duffy transformation, an additional term (1-z)^{n-1} shows up.  To properly
capture this term, you either need Gauss-Legendre rules of higher order,
or you interpret the term as a weight function as use Gauss-Jacobi quadrature.
