MNELIB::MNETriangle is the per-face record produced by MNESourceSpace and MNEBemSurface readers so downstream code (forward solver, projection-to-surface, rendering) does not have to recompute these quantities. Carries the three vertex indices, the centroid, the un-normalised and normalised triangle normals and the area.
