> Small change to add vector operations. With this small change, can now do
> things like:
> val v1 = DenseVector(0.1, 0.1)
> val v2 = DenseVector(0.2, 0.2)
> val v3 = v1 + v2
> instead of what is now has to be done:
> val v1 = DenseVector(0.1, 0.1)
> val v2 = DenseVector(0.2, 0.2)
> val v3 = (v1.asBreeze + v2.asBreeze).fromBreeze
