Detailed Description
1D Gaussian integration class for linear "triangular" elements. Two integration points. This integration scheme can integrate up to second-order polynomials exactly and is therefore a suitable "full" integration scheme for linear (two-node) elements in which the highest-order polynomial is quadratic.
