How to use the superfly-timeline.Resolver.getTimelineInWindow function in superfly-timeline

export const ComponentTimelineSimulate = withTracker(() => {

	// These properties will be exposed under this.props
	// Note that these properties are reactively recalculated
	let timeline = transformTimeline(
		Timeline.find({}, { sort: { _id: 1 } }).fetch()
	)

	// pre-process the timeline
	let now = getCurrentTimeReactive()

	let tl = Resolver.getTimelineInWindow(timeline)

	let state = Resolver.getState(tl, now)

	return {
		now: now,
		state: state
	}
})(
