Overview

This class holds the logic to present the diff for any activity log. The data needed for this class to work should be sent by ‘Decidim::Log::BasePresenter` or any of its children.

In order to be able to use your own class to present a diff, you’ll need to overwrite ‘BasePresenter#diff_presenter` to return your custom diff presenter. The only requirement for custom renderers is that they should respond to `present`.
