// File name:     G4CrossSectionDataStore

// Modifications:
// 23.01.2009 V.Ivanchenko move constructor and destructor to source,
//                         use STL vector instead of C-array
//
// August 2011  Re-designed
//              by G. Folger, V. Ivantchenko, T. Koi and D.H. Wright
 
// Class Description
// This is the class to which cross section data sets may be registered. 
// An instance of it is contained in each hadronic process, allowing
// the use of the AddDataSet() method to tailor the cross sections to
// your application.
