		varying	values
	)

Creates a Product-quadrature.

Parameters

QuadratureType	int Quadrature identifier.
values	varying Varying options based on the quadrature type.

QuadratureType:

GAUSS_LEGENDRE
Gauss-Legendre quadrature for the polar angles and no quadrature rule for the azimuthal angle. Suitable only for 1D simulations. Expects to be followed by the number of angles Np. Optionally a verbosity flag can be added.

GAUSS_LEGENDRE_LEGENDRE
Gauss-Legendre quadrature for both the polar and azimuthal dimension. Expects to be followed by number of Azimuthal and Polar angles. Optionally a verbosity flag can be added.

GAUSS_LEGENDRE_CHEBYSHEV
Gauss-Legendre quadrature for the polar angle but Gauss-Chebyshev for the azimuthal angle. Expects to be followed by number of Azimuthal and Polar angles. Optionally a verbosity flag can be added.

CUSTOM_QUADRATURE
Expects to be followed by three lua tables. The first table is an array, of length Na, of the azimuthal angles (radians). The second table is an array, of length Np, of the polar angles (radians). The third table is an array, of length Na*Np, and contains the weight associated with each angle pair. Optionally a verbosity flag can be added.

Returns: Returns a unique handle to the created product quadrature rule
