JaroWinkler distance

[sboudouk]

It looks like jaroWinkler distance behave the same as similarity.

exact match in distance will results in 1 instead of 0.

Using cosine, exact match in distance will result in 0, which is correct.

Even if jaroWinkler doesn't support distance by default, maybe you want to provide a coherent interface and just reverse similarity result for distance method.
