	determines the 2 2D-points resulting of the intersection of the triangle (Point1,Point2,Point3) by the plane
void	Insert (const gp_Pnt2d &OldPnt, const gp_Pnt2d &ComPnt, const gp_Pnt2d &NewPnt)
	sees whether OldPnt and NewPnt begins or ends a section created before and adds the 2 others points. If not, creates a section
Standard_Integer	Concat (const gp_Pnt2d &BegPnt, const gp_Pnt2d &EndPnt, gp_Pnt2d &OutPnt)
	sees whether BegPnt or EndPnt begins or ends a section created before, and returns the other point to continue the construction Returns 2 if the construction is 'Forward' Returns 1 if the construction is 'Previous' Returns 0 if not and creates a section
