Detailed Description

Store reconstructed trajectories from track finding/fitting.

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.
