Andrew Dunham	b7104cde4a	util/topk: add package containing a probabilistic top-K tracker This package uses a count-min sketch and a heap to track the top K items in a stream of data. Tracking a new item and adding a count to an existing item both require no memory allocations and is at worst O(log(k)) complexity.

util/topk: add package containing a probabilistic top-K tracker

This package uses a count-min sketch and a heap to track the top K items
in a stream of data. Tracking a new item and adding a count to an
existing item both require no memory allocations and is at worst
O(log(k)) complexity.
