Query()

void Sleak::Physics::DynamicAABBTree::Query	(	const AABB &	queryAABB,
		const std::function< bool(int)> &	callback ) const

Visits every leaf whose fat AABB overlaps queryAABB; stop early by returning false from callback.

void Sleak::Physics::DynamicAABBTree::RayCast	(	const Vector3D &	origin,
		const Vector3D &	direction,
		float	maxDist,
		const std::function< bool(int)> &	callback ) const

Walks the tree along a ray, visiting candidate leaves within maxDist.
