Replying to [comment:11 kcrisman]:
> Hmm, but in that case what does normalization even mean? Then we should
just get rid of this function entirely.
If you think of vectors as specifying directions, then normalization gives
you a "random but fixed" vector pointing in the same direction as the
original. If you store a lot of directions, then comparing normalized
vectors is quicker than using dot-products.
