STL Reader and Writer tools have been refactored to improve performance and usability: - Basic reading of STL file is separated to abstract class RWStl_Reader which is not bound to particular data structures; the target data model can be bound via inheritance. - RWStl package uses class Poly_Triangulation to represent triangular mesh. - Obsolete data structures and tools (packages StlMesh and StlTransfer) are removed.
