Definition of an intersection line between two surfaces. A line may be either geometric : line, circle, ellipse, parabola, hyperbola, as defined in the class GLine, or analytic, as defined in the class ALine, or defined by a set of points (coming from a walking algorithm) as defined in the class WLine.
