/**
 * A {@linkplain GriddedSurface gridded surface} that uses cubic polynomial splines as the
 * horizontal and vertical curves. The initial tangents for the splines are often replaced by an
 * extra pair of rows (and columns) of control points.
 *
 * The horizontal and vertical curves require initial and final tangent vectors for a complete
 * definition. These values are supplied by the four methods defined in this interface.
