The methods propagateWithPath() are identical to the corresponding methods propagate() in what concerns the resulting TrajectoryStateOnSurface, but they provide in addition the exact path length along the trajectory. Only use the generic method if the surface type (plane or cylinder) is not known at the calling point.

The following three methods are equivalent to the corresponding methods above, but if the starting state is a TrajectoryStateOnSurface, it's better to use it as such rather than use just the FreeTrajectoryState part. It may help some concrete propagators. Only use the generic method if the surface type (plane or cylinder) is not known at the calling point.
