4.  def aggregator[A, B, C](batchSize: Int, agg: Aggregator[A, B, C]): Aggregator[A, Batched[B], C]

   This aggregator batches up agg so that all the addition can be performed at once.

   This aggregator batches up agg so that all the addition can be performed at once.

   It is useful when sumOption is much faster than using plus (e.g. when there is temporary mutable state used to make summation fast).

5.  def apply[T](t: T): Batched[T]

   Constructed a batch from a single value.

8.  def compactingMonoid[A](batchSize: Int)(implicit arg0: Monoid[A]): Monoid[Batched[A]]

   Compacting monoid for batched values.

   Compacting monoid for batched values.

   This monoid ensures that the batch's tree structure has fewer than batchSize values in it. When more values are added, the tree is compacted using m.

   It's worth noting that x + 0 here will produce the same sum as x, but .toList will produce different lists (one will have an extra zero).

9.  def compactingSemigroup[A](batchSize: Int)(implicit arg0: Semigroup[A]): Semigroup[Batched[A]]

   Compacting semigroup for batched values.

   Compacting semigroup for batched values.

   This semigroup ensures that the batch's tree structure has fewer than batchSize values in it. When more values are added, the tree is compacted using s.

12.  implicit def equiv[A](implicit e: Equiv[A], s: Semigroup[A]): Equiv[Batched[A]]

    Equivalence for batches.

    Equivalence for batches.

    Batches are equivalent if they sum to the same value. Since the free semigroup is associative, it's not correct to take tree structure into account when determining equality.

    One thing to note here is that two equivalent batches might produce different lists (for instance, if one of the batches has more zeros in it than another one).

19.  def items[T](ts: TraversableOnce[T]): Option[Batched[T]]

    Constructed an optional batch from a collection of values.

    Constructed an optional batch from a collection of values.

    Since batches cannot be empty, this method returns None if ts is empty, and Some(batch) otherwise.

20.  def monoidAggregator[A, B, C](batchSize: Int, agg: MonoidAggregator[A, B, C]): MonoidAggregator[A, Batched[B], C]
