This class handles the particle stack for the transport simulation. For the stack FILO functunality, it uses the STL stack. To store the tracks during transport, a TParticle arry is used. At the end of the event, tracks satisfying the filter criteria are copied to a R3BMCTrack array, which is stored in the output.

The filtering criteria for the output tracks are:

• primary tracks are stored in any case.
• secondary tracks are stored if they have a minimal number of points (sum of all detectors) and a minimal energy, or are the

The storage of secondaries can be switched off. The storage of all mothers can be switched off. By default, the minimal number of points is 1 and the energy cut is 0.
