std::auto_ptr< pat::OverlapList > pat::GenericOverlapFinder< Distance >::find	(	const Collection &	items,

	)		const

Indices of overlapped items, and of the nearest item on they overlap with Items are considered to overlap if distance(x1,x2) < 1 both Collections can be vectors, Views, or anything with the same interface
