int LCIOTrackPropagators::PropagateLCIOToCylinder	(	IMPL::TrackStateImpl &	ts,
		float	r,
		float	x0,
		float	y0,
		int	direction = 0,
		double	epsilon = 1.0e-8
	)

Propagate trackstate to a new reference point taken as its crossing point with a cylinder of infinite length centered at x0,y0, parallel to the z axis.

For direction== 0 the closest crossing point will be taken For direction== 1 the first crossing traversing in positive s will be taken For direction==-1 the first crossing traversing in negative s will be taken
