This PR adds NV, KV and VV correlation functions. Here V is a vector, i.e. any spin-1 field.
I didn't bother implementing VG correlations (spin-1 with spin-2), since that seems not likely to be useful. But as usual, if someone wants it, please feel free post an issue. It wouldn't be hard to add. I just didn't want to waste time doing something that I doubt anyone will want.
I also didn't add 3pt functions for V. Again, not particularly hard to do, but I'll wait until there is a request from a user.
