//      Bertini Cascade diproton class implementation file
//
//      History: first implementation, inspired by G4Diproton
//      17 Nov 2009:  Michael Kelsey
//  06 Apr 2010:  Do G4Ions initialization in ctor.
//  13 Apr 2010:  Per Kurashige, inherit from G4VShortLivedParticle.
//  06 May 2010:  Remove created particle from master table.
//      25 May 2012:  Add flags to suppress particle-table error message.
//  01 May 2013:  Remove G4ThreadLocal from static pointer.
