Direction	propagationDirection = Direction::Forward()
	Direction of the propagation along the trajectory.
const Surface *	startSurface = nullptr
	Surface the navigation run starts on, if any.
const TrackingVolume *	startVolume = nullptr
	Hint for the start volume which short-cuts the volume search, if known.

Detailed Description

Per-run inputs to the navigator initialization.

A navigation state can serve more than one run, so everything that changes from run to run is passed here instead of through the navigator options.
