Feature: k-anonymity

[dbkaplun]

Hello,

It would be great if this software supported k-anonymity, so that no row in the output were uniquely distinguishable. It should be possible to output the maximum k for a given dataset, as well.

Thanks!

@dbkaplun Awesome idea! We're going to have a think about what it would take to do this properly at some point, so stay tuned.
