Detailed Description

Struct for truth track fitting/finding result with Acts::KalmanFitter/Acts::CombinatorialKalmanFilter.

It contains a MultiTrajectory with a vector of entry indices for individual trajectories, and a map of fitted parameters indexed by the entry index. In case of track fitting, there is at most one trajectory in the MultiTrajectory; In case of track finding, there could be multiple trajectories in the MultiTrajectory.

Note: The MultiTrajectory is thought to be empty if there is no entry index
