Adds
TriangleIntegration::N4, Dunavant's 6-point degree-4 rule with positive weights (Int. J. Numer. Meth. Eng. 21, 1985). It also serves order 3, so triangles now support orders up to 4. NewTriangleIntegrationTestchecks each rule's exactness and the selected rule, and runsIntegrator::processwith orders 3 and 4.
