Detailed Description

A 6-dimensional state vector of a helix given at some point in space along the helix, and the associated error matrix. The error can be obtained in two different parametrizations: CurvilinearTrajectoryError and CartesianTrajectoryError (see descriptions of corresponding classes). The FreeTrajectoryState can be instantiated with either of these error parametrisations; it converts from one to the other internally.
