Reducer

abstract class Reducer[C, M] extends AnyRef

A Reducer[C,M] is a Monoid[M] that maps values of type C through unit to values of type M. A C-Reducer may also supply operations which tack on another C to an existing 'Monoid' M on the left or right. These specialized reductions may be more efficient in some scenarios and are used when appropriate by a 'Generator'. The names 'cons' and 'snoc' work by analogy to the synonymous operations in the list monoid.

Minimal definition: 'unit' or 'snoc'
