// G4BiasingProcessSharedData
//
// Class Description:
//        This class represents the data that the G4BiasingProcessInterface
//    objects attached to a same particle / hold by a same G4ProcessManager
//    share. It allows the active G4BiasingProcessInterface objects to share
//    information on operations that are common the these instances:
//        - the current and previous G4VBiasingOperator objects (their
//          pointers are collected once, at the beginning of the PostStepGPIL
//          by the first interface invoked)
//        - add the list of cooperating G4BiasingProcessInterface objects,
//          acting on a same particle type.
//        G4BiasingProcessInterface is friend class of this one.
