Classifier has been corrected to not take into account a probing point if the probing line appears to be tangent to the boundary at this point.
But allow to use tangent point if all points on the edge are tangent.
Modify bad test cases.
Test case for issue CR26206
4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)
5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.
6. Test cases were modified according to the modern behavior.
7. Changes in BRepLib_CheckCurveOnSurface to use adaptors instead of geometric entities
9. Added methods to access directly poles, knots, multiplicities of BSpline curves and surfaces
Added subgroups volumemaker, gdml_private and gdml_public
Moved scripts from public repository ti test cases
Added more TODOs to unstable test cases
Small corrections for unstable test cases
