Detailed Description

Class to perform more detailed timing studies of the Geant4 simulation.

This class overrides the default G4SteppingVerbose implementation which is used by Geant4 to display stepping information. It measures the time for each step and calls a given callback function with a pointer to the track, the volume in which the step occured and the time needed for that step.

Measuring the time in each step causes a overhead of 10%-20% so this should not be used in production
