Initial commit; spec'd `clone_flagger()`.
Intermediate commit. Writing and testing pieces of code.
Incomplete commit, with print statements still in there
More final version of `clone_flagger()` with print statements removed.
Wrote and tested `clone_killer()` - works!
Wrote `clone_hunterkiller()` that combines the two other functions.

Tested, works.
Added support for UKvar numbering, and cloned `gen_oncvar_all()` ...

to `gen_ukvar_all()` (with a simple find-and-replace) to gen UKvar plots.
Tested, works.
