 * \brief Semi-conformal mesh node.
 *
 * A semi-conformal mesh node is defined by the master face it belongs to
 * (see ITiedInterface) and not its iso-barycentric coordinates within that
 * face. These coordinates are always between -1 and 1, and their value depends
 * on the face type. For a 3D quadrilateral face, the definition is that of
 * GeometricUtilities::QuadMapping.
