Detailed Description

3D Gaussian integration class for tets. 45 integration points. This integration scheme can integrate up to eighth-order polynomials exactly and is therefore a suitable "full" integration scheme for quartic elements in which the highest-order polynomial is fourth order. The numbers are from Keast CMAME 55 pp339-348 (1986)
