0027079: Bad approximation of intersection curves with variable curvature

Browse Source 
1. Method Approx_ComputeLine::Perform is modified: now it contains also recursive calls after new line computation made by new method ApproxInt_MultiLine::MakeMLOneMorePoint.
    2. New method MakeMLOneMorePoint is added to ApproxInt_MultiLine: it builds new sub-line as a part of main line with new point added into the middle of the longest interval between existing points.
    3. Method ShapeConstruct_ProjectCurveOnSurface::ApproxPCurve is modified to avoid regressions: now it takes care of the set of initial points to be enough close to each other so that an interval between two adjacent points is less than half-period of the surface.
    4. Modification in ShapeConstruct_ProjectCurveOnSurface: correction of pcurves of edges which extremities are in the singularities of surface.
