##! Keep the top-k (i.e., most frequently occurring) observations.
##!
##! This plugin uses a probabilistic algorithm to count the top-k elements.
##! The algorithm (called Space-Saving) is described in the paper Efficient
##! Computation of Frequent and Top-k Elements in Data Streams", by
##! Metwally et al. (2005).
