0030645: Modeling Algorithms - B-spline segmentation produces wrong parametrization

Method Segment() of B-spline curve and surface has been extended by parameter theTolerance (theUTolerance and theVTolerance for surface), which defines the proximity between knots of a NURBS and boundaries of cutting segment. The default value of the tolerance is Precision::PConfusion().
Test cases have been added to check segmenting of B-spline surface and curves both 2D and 3D.

1. Approx_ComputeCLine.gxx, Approx_FitAndDivide.hxx, Approx_FitAndDivide2d.hxx, BRepFill_ComputeCLine.hxx
It is base modification, which allows improve performance of approximation with help of Approx_ComputeCLine. The main idea of improvement is using degree selection by inverse order - from maxdegree to mindegree. If tolerance for maxdegree is not reached, there is no sense to make approximation for current number of knots with lower degree, it is necessary to cut parametric interval.

2. ProjLib_ComputeApprox, ProjLib_ComputeApproxOnPolarSurface, ProjLib_ComputeApproxOnPolarSurface, ProjLib_ProjectOnPlane
It is additional modification of methods using Approx_ComputeCLine.
Mainly, modifications concern to more optimal choosing parameters for approximation algorithm.

3. BRepCheck_Face
Small improvement of method Intersect(...), which intersects two wires on face.

4. BRepTopAdaptor_FClass2d
Impovement of treatment infinitely narrow faces.

5. ChFi3d/ChFi3d_Builder_6.cxx

Improvement of performance for cases of searching common parts between line  and analytical curve

7. GeomliteTest_CurveCommands.cxx
