Computing is unified. ComputeFastTol3d() method was deleted.
If intersection result contains 3D- and corresponded two 2D-curves then tolerance will be computed with using BRepLib_CheckCurveOnSurface algorithm (check same-parameter).
If intersection result contains only 3D-curve (getting 2D-curve can be switched off by users) then tolerance will be computed with using GeomAPI_ProjectPointOnSurf algorithm (projects some point of 3D-curve on the surface and finds maximal distance).
Some workarounds have been deleted.
Some test case have been changed.
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
