    using FLANN

    X = readdlm(Pkg.dir("FLANN", "test", "iris.csv"), ',')
	v = X[:, 84]
	k = 3
	r = 10.0

	idxs, dsts = nearest(X, v, k, FLANNParameters())

	# or

	t = flann(X, FLANNParameters(), Minkowski(3))
	inds, dists = nearest(t, v, k)

	# or

	idxs, dsts = inball(t, v, r)

	# Do not forget to close index!
	close(t)
