Subject: [FIAT-dev] worked on tangents to faces of tetrahedra. They are computed automatically from the reference geometry. the first tangent on a face runs from vertex 0 to vertex 1 of that face. The second runs in the direction from the edge between vertex 0 and vertex 1 to vertex 2, perpendicular to the edge.
