MNELIB::MNESurfaceOrVolume is the direct port of the mneSurfaceOrVolumeRec / mneSourceSpaceRec structure of MNE-C and is the common base used by MNELIB::MNESourceSpace and MNELIB::MNEBemSurface. It carries the union of fields used by both flavours - vertices, triangles, normals, voxel size and lattice geometry - so a single loader can return either kind without templated machinery.
