proc initTopK[T](k = 10; partn = last): TopK[T]: Initialize a TopK-accumulator for top-k; Usage is simply:
var t = initTopK(); for e in 1..99: t.push e for e in t: echo e

proc push[T](t: var TopK[T]; e: sink T): Incorporate element e into t for eventual exact for e in t: ... Source Edit
proc saw[T](t: TopK[T]): int: push count since last init|clear Source Edit
