FThinZone2D::FThinZone2D

FThinZone2D::FThinZoneSides are maded with a copy of TArray into TArray to break the link with TFactory of FThinZone2DFinder So [FThinZone2D](API\Runtime\CADKernel\Mesh\Structure\FThinZone2D) can be transfered into the [FTopologicalFace](API\Runtime\CADKernel\Topo\FTopologicalFace)
