CMSParams

Configuration parameters for CMS.

K: The type used to identify the elements to be counted.
hashes: Pair-wise independent hashes functions. We need N=depth such functions (depth can be derived from delta).
eps: One-sided error bound on the error of each point query, i.e. frequency estimate.
delta: A bound on the probability that a query estimate does not lie within some small interval (an interval that depends on eps) around the truth.
maxExactCountOpt: An Option parameter about how many exact counts a sparse CMS wants to keep.
