The following class provides QuadratureRules for pyramids by using Gauss Jacobi Quadrature and Gauss Legendre Quadrature
The idea of this quadrature is to divide the pyramid into two tetrahdrons given by {x,0,1},{y,0,x},{z,0,1-x} and {x,0,1},{y,x,1},{z,0,1-y} and carry out integration on those using GaussQuadratureTetrehedron
