Overview

This class is used as a base for other value presenters, and as a default presenter when the presenter for the given value is not specified or is not found.

Value presenters are dynamically found from the value type set in the ‘fields_mapping` method in the resource presenter. If the value is a symbol, the system will try to infer the correct presenter and use it. If it’s a String, it will treat it as a class name, and will try to fetch that presenter. If the system fails in either case, it will use the ‘DefaultPresenter`.
