Get magnetic field

Get the primary tracks

Get the primary trajectories (produced by the Refitter)

Get the AssociationMap between primary tracks and trajectories

Get the AssociationMap between seeds and primary trajectories

Get the secondary tracks

Definition of the output

Loop on all primary trajectories

1. Get the primary track from the trajectory
2. Get the seeds from the trajectory
3. Get the secondary tracks
4. Get the vertex and the likelihood
5. Build the nuclear interaction
6. Search for additional secondary tracks in an other track collection and recompute the nuclear interaction
