KLL sketch implementation

[silap-quarry]

Hello,

I have two questions:

1. Is KLL sketch gonna be added any time soon? I didn't see it in the 1.0 roadmap.
2. Do you accept PRs that are outside your roadmap? (In this case, a KLL sketch port PR)

Yes.

Actually I should add it to 1.0 Roadmap.

There is a PR for it #76 but it's stale so if you'd submit yours, feel free to do it.
