Sampling enhancements

Allow specification of a key with -k for doing sampling between a single
datum and the rest of the database.  (The implementation is slightly
icky, as mentioned in the previous commit message; hopefully this
situation will not remain for too long).

While we're at it, allow -r/--resultlength as a synonym for --nsamples
(if --nsamples is not given) in order better to reflect the analogy
between querying and sampling.
