> Sample:   
> val s1 = new SparseVector(4, Array(0,1,2,3), Array(1.0, 2.0, 3.0, 4.0))
> val s2 = new SparseVector(1, Array(0), Array(9.0))
> val d1 = new DenseVector(Array(1.0, 2.0, 3.0, 4.0))
> val d2 = new DenseVector(Array(9.0))
> println(s1 == d1 && s2 == d2)
> println(Vectors.sqdist(s1, s2))
> println(Vectors.sqdist(d1, d2))
> result:
>  true
>  93.0
>  64.0
> More precisely, for the extra part, Vectors.sqdist would include it for 
> sparse vectors and exclude it for dense vectors. I'll send a PR and we can
