bool TrajectorySeedProducer::testWithRegions	(	const TrajectorySeedHitCandidate &	innerHit,
		const TrajectorySeedHitCandidate &	outerHit
	)		const

method inserts hit into the tree structure at an empty position.

Parameters

trackerRecHits	list of all TrackerRecHits.
hitIndicesInTree	hit indices which translates the tree node to the hits in trackerRecHits. Empty positions are identified with '-1'.
node	where to look for an empty position. Important for recursive tree traversing (Breadth-first). Starts with the root.
trackerHit	hit which is tested.

Returns: pointer if this hit is inserted at a leaf which means that a seed has been found. Returns 'nullptr' otherwise.
