A module internal to Incremental. Users should see Incremental_intf.
A Balanced_reducer.t is a mutable non-empty array that tracks the result of folding an associative operation (reduce) over the array as its elements change.

'a tcreate_exn ~len ~reduce creates an array containing len Nones and prepares an incremental fold with reduce. It raises if len < 1.
val set_exn : 'a t -> int -> 'a -> unitset_exn t i a updates the value at index i to Some a. It raises if i is out of bounds.
val compute_exn : 'a t -> 'acompute_exn t computes the value of the fold. It raises if any values of the array are None.
