// class G4LogicalVolume
//
// Class description:
//
// Represents a leaf node or unpositioned subtree in the geometry hierarchy.
// Logical volumes are named, and may have daughters ascribed to them.
// They are responsible for retrieval of the physical and tracking attributes
// of the physical volume that it represents: solid, material, magnetic field,
// and optionally, user limits, sensitive detectors.
//
// Get and Set functionality is provided for all attributes, but note that
// most set functions should not be used when the geometry is `closed'.
// As a further development, `Guard' checks can be added to ensure
// only legal operations at tracking time.
//
// On construction, solid, material and name must be specified.
//
// Daughters are ascribed and managed by means of a simple
// GetNoDaughters,Get&SetDaughter(n),AddDaughter interface.
//
// Smart voxels as used for tracking optimisation are also an attribute.
//
// Logical volumes self register to the logical volume Store on construction,
// and deregister on destruction.
//
// NOTE: This class is currently *NOT* subclassed, since not meant to
// act as a base class. Therefore, the destructor is NOT virtual.
//
// Data members:
//
// G4std::vector<G4VPhysicalVolume*> fDaughters
// - Vector of daughters. Given initial size of 0.
// G4FieldManager *fFieldManager
// - Pointer (possibly NULL) to (magnetic or other) field manager object.
// G4Material *fMaterial
// - Pointer to material at this node.
// G4String fName
// - Name of logical volume.
// G4VSensitiveDetector *fSensitiveDetector
// - Pointer (possibly NULL) to `Hit' object.
// G4VSolid *fSolid
// - Pointer to solid.
// G4UserLimits *fUserLimits
// - Pointer (possibly NULL) to user Step limit object for this node.
// G4SmartVoxelHeader *fVoxel
// - Pointer (possibly NULL) to optimisation info objects.
// G4double fSmartless
// - Quality for optimisation, average number of voxels to be spent
// per content.
// const G4VisAttributes* fVisAttributes
// - Pointer (possibly NULL) to visualization attributes.
// G4FastSimulationManager *fFastSimulationManager
// - Pointer (possibly NULL) to G4FastSimulationManager object.
// G4bool fIsEnvelope
// - Flags if the Logical Volume is an envelope for a FastSimulationManager.
// G4double fBiasWeight
// - Weight used in the event biasing technique.
// History:
// 18.04.01 G.Cosmo: Migrated to STL vector
// 12.02.99 S.Giani: Added user defined optimisation quality
// 09.11.98 J. Apostolakis: Changed G4MagneticField to G4FieldManager
// 09.11.98 M. Verderi & JA. : added BiasWeight member and Get/Set methods
// 10.20.97 P. MoraDeFreitas : added pointer to a FastSimulation
// (J.Apostolakis) & flag to indicate if it is an Envelope for it
// 19.11.96 J.Allison Replaced G4Visible with explicit const G4VisAttributes*.
// 19.08.96 P.Kent Split -> hh/icc/cc files; G4VSensitiveDetector change
// 11.07.95 P.Kent Initial version.
