/// Uer detector construction class
///
/// (Description)
///
///    Detector construction for example RE02.
///   
///  [Geometry] 
///    The world volume is defined as 200 cm x 200 cm x 200 cm box with Air.
///  Water phantom is defined as  200 mm x 200 mm x 400 mm box with Water.
///  The water phantom is divided into 100 segments in x,y plane using
///  replication,
///  and then divided into 200 segments perpendicular to z axis using nested 
///  parameterised volume.  
///   These values are defined at constructor,
///   e.g. the size of water phantom (fPhantomSize), and number of segmentation
///  of water phantom (fNx, fNy, fNz).
///
///  By default, lead plates are inserted into the position of even order 
///  segments.
///  NIST database is used for materials.
///
///
///  [Scorer]
///   Assignment of G4MultiFunctionalDetector and G4PrimitiveScorer 
///  is demonstrated in this example.
///      -------------------------------------------------
///      The collection names of defined Primitives are
///       0       PhantomSD/totalEDep 
///       1       PhantomSD/protonEDep
///       2       PhantomSD/protonNStep
///       3       PhantomSD/chargedPassCellFlux
///       4       PhantomSD/chargedCellFlux 
///       5       PhantomSD/chargedSurfFlux 
///       6       PhantomSD/gammaSurfCurr000
///       7       PhantomSD/gammaSurfCurr001
///       9       PhantomSD/gammaSurdCurr002

/// - G4VPhysicalVolume* Construct()
///     retrieves material from NIST database,
///     constructs a water phantom "phantom" in the world volume "world" and
///     sets detector sensitivities with G4MultiFunctionalDetector
///
/// - void SetPhantomSize(G4ThreeVector size)
///     sets the water phantom size which is defined in G4Box
///
/// - const G4ThreeVector& GetPhantomSize() const
///     gets the water phantom size
///
