//! Provides information about the continuity of a curve:
//! - C0: only geometric continuity.
//! - G1: for each point on the curve, the tangent vectors
//! "on the right" and "on the left" are collinear with the same orientation.
//! - C1: continuity of the first derivative. The "C1" curve is
//! also "G1" but, in addition, the tangent vectors " on the
//! right" and "on the left" are equal.
//! - G2: for each point on the curve, the normalized
//! normal vectors "on the right" and "on the left" are equal.
//! - C2: continuity of the second derivative.
//! - C3: continuity of the third derivative.
//! - CN: continuity of the N-th derivative, whatever is the
//! value given for N (infinite order of continuity).
//! Also provides information about the continuity of a surface:
//! - C0: only geometric continuity.
//! - C1: continuity of the first derivatives; any
//! isoparametric (in U or V) of a surface "C1" is also "C1".
//! - G2: for BSpline curves only; "on the right" and "on the
//! left" of a knot the computation of the "main curvature
//! radii" and the "main directions" (when they exist) gives the same result.
//! - C2: continuity of the second derivative.
//! - C3: continuity of the third derivative.
//! - CN: continuity of any N-th derivative, whatever is the
//! value given for N (infinite order of continuity).
//! We may also say that a surface is "Ci" in u, and "Cj" in v
//! to indicate the continuity of its derivatives up to the order
//! i in the u parametric direction, and j in the v parametric direction.
