//
// Class DefaultVisitor
//   The default interface for a BeamlineVisitor.
//   A default implementation for all visitors that can iterate over a
//   beam line representation.
//   This abstract base class implements the default behaviour for the
//   structural classes Beamline and FlaggedElmPtr.
//   It also holds the data required for all visitors in a protected area.
