Detailed Description

The core class of the new SimplifiedGeometryPropagator.

Coordinates the propagation of all particles, this means it does the following loop: 1) Get particle from ParticleManager 2) Call LayerNavigator to move particle to next intersection with layer 3) Loop over all the interactions and add secondaries to the event 4) Repeat steps 2), 3) until particle left the tracker, lost all its energy or is about to decay 5) If particle is about to decay: do decay and add secondaries to the event 6) Restart from 1) with the next particle 7) If last particle was propagated add SimTracks, SimVertices, SimHits,... to the event
