Detailed Description

2D Gaussian integration class for quadratic triangles. Seven integration points. This integration scheme can integrate up to fifth-order polynomials exactly and is therefore a suitable "full" integration scheme for quadratic (six-node) elements in which the highest-order polynomial is fourth order.
