Use the scoring plane hit at the target to extract (x, y, z, px, py, pz) and create a track seed.

In this case, the SimParticle is used to extract the charge of the particle.

Parameters
particleThe SimParticle to extract the charge from.
hitThe SimTrackerHit used to create the seed. Create a truth track from the given position, momentum and charge.
posThe position at which the particle was created.
pThe momentum of the particle at the point of creation.
chargeThe charge of the particle.
