Overview

Base implementation for a Collection Presenter.

This class can be extended in your application to inherit the convenience of delegating to a collection policy’s resolved scope and having a default ‘present` method available for wrapping other objects according to the configured factory. To specify a factory, override `presenter_factory`.
