Description
This library is useful for counting elements by categories, constructing relations and transposing them. Binning are constructed from streams of values. A binning can be seen as a generalized histogram: values are mapped to bins, and each bin keeps a summary value that is updated when an element is added (like a count, the list of elements, their mean, etc).

Binning
A tiny library to count objects (for histograms) or sort them by category (build an association or relation). Here is a typical use:
let histogram xs =
List.to_seq xs
|> Binning.counts
|> List.of_seq
(* val histogram : 'a list -> ('a * int) list = <fun> *)
