//! This algorithm is used to compute the transition <br>
//! of a 3D surface intersecting a topological surfacic <br>
//! boundary on a 3D curve ( intersection curve ). <br>
//! The boundary is described by a set of faces <br>
//! each face is described by <br>
//! - its support surface, <br>
//! - an orientation defining its matter side. <br>
//! The geometric elements are described locally at the <br>
//! intersection point by a second order development. <br>
//! A surface is described by the normal vector, the <br>
//! principal directions and the principal curvatures. <br>
//! A curve is described by the tangent, the normal <br>
//! and the curvature. <br>
//! The algorithm keeps track of the two faces elements <br>
//! closest to the part of the curve "before" and "after" <br>
//! the intersection, these two elements are updated <br>
//! for each new face. <br>
//! The position of the curve can be computed when at <br>
//! least one surface element has been given, this <br>
//! position is "In","Out" or "On" for the part of the <br>
//! curve "Before" or "After" the intersection. <br>
