Added PLY writing tools RWPly_CafWriter and RWPly_PlyWriterContext. Added tool BRepLib_PointCloudShape generating point cloud from shape in two ways: - random points on surface with specified density; - points from triangulation nodes. StdPrs_ToolTriangulatedShape::ComputeNormals() has been moved to BRepLib_ToolTriangulatedShape for reusing outside of AIS. Command vpointcloud has been extended to use new generation tool. Command writeply has been added to write triangulation or point set into PLY format.
