0029839: Modeling Algorithms - Unexpected Circle to BSpline surface extrema behavior

Browse Source 
Extrema_ExtCS.cxx: treatment of small line segments is added;
Extrema_GenExtCS.cxx: treatment of particular cases curve-quadric and conic-surface are added
Extrema_GlobOptFuncCQuadric, Extrema_GlobOptFuncConicS: new distance functions for particular cases are added

BOPAlgo_PaveFiller_5.cxx : treatment of large common parts edge-face is improved
ElSLib.cxx : method TorusParameters(...) is modified to avoid divide by zero
math_PSOParticlesPool.cxx : initialization of array is added
