Updated values in some particularly sensitive compressible flow solver tests.

Tidied up QuadExp, TriExp, HexExp LaplacianMatrixOp/HelmholtzMatrixOp ops.

Updated TetGeom::SetUpLocalEdges to check that edge 0 of face 0 is the same as edge 0 of face 1 in tets and that edge 0 of faces 1 2 3 make up face 0 of the same tet
