Detailed Description

Gaussian Quadrature Integration Strategy.

This class inherits from vtkIntegrationStrategy and override several function for specific cell types to use the Gaussian Quadrature rule which enables the correct computation of higher order cells and non simplicial shapes. Note that not all cells are properly handled by the strategy, and the computation falls back to the linear strategy for those. Reference to the quadrature method: https://en.wikipedia.org/wiki/Gaussian_quadrature Reference for quadrature weights computation : https://www.mm.bme.hu/~gyebro/files/ans_help_v182/ans_thry/thy_et1.html Note that we specifically implement the Gauss-Legendre quadrature
