0010  *  Concrete class to encapsulate the creation of RefCountedLinearizedTrackState,
0011  *  which is a reference-counting pointer.
0012  *  This class handles the possibility that the input track is described by
0013  *  not one state, but a Gaussian Mixture of state (see BasicMultiTrajectoryState).
0014  *  Should always be used in order to create a new RefCountedLinearizedTrackState,
0015  *  so that the reference-counting mechanism works well.
