// G4BOptnForceCommonTruncatedExp
//
// Class Description:
// A G4VBiasingOperation physics-based biasing operation. It
// handles several processes together, biasing on the total
// cross-section of these processes (instead of biasing them
// individually).
// The biasing interaction law is a truncated exponential
// one, driven by the total cross-section and which extends
// in the range [0,L].
// Process are registered with the AddCrossSection method.
// As cross-sections are all known at the end of the
// PostStepGPIL loop, the step limitation is made at the
// AlongStepGPIL level.
