// Class Description
// Manager of LEND (Low Energy Nuclear Data) target (nucleus) 
// LEND is Geant4 interface for GIDI (General Interaction Data Interface) 
// which gives a discription of nuclear and atomic reactions, such as
//    Binary collision cross sections
//    Particle number multiplicity distributions of reaction products
//    Energy and angular distributions of reaction products
//    Derived calculational constants
// GIDI is developped at Lawrence Livermore National Laboratory
// Class Description - End

// 071025 First implementation done by T. Koi (SLAC/SCCS)
// 101118 Name modifications for release T. Koi (SLAC/PPA)
