Approximation parameters: degmin, degmax, max number of segments, boundary condition, maximal distance of projecting are added in interface of classes ProjLib_ProjectedCurve, ProjLib_ComputeApprox, ProjLib_ComputeApproxOnPolarSurface Algorithm of Approx/Approx_ComputeCLine is modified in order to treat maximal number of segments allowed for cutting. Algorithm of method BOPTools_AlgoTools2D::MakePCurveOnFace(...) is modified in order to manage cases with big edge tolerances. Test case added Some test cases were modified according to new behavior of algorithms
