Overview

Class builder for Slot models

Every composite content slot is defined by its own class, subclass of CompositeContent::Slot. This allows to use of a dedicated block class where we can set validations on block types and to rely on ActiveRecord default behaviors for Single Table Inheritance models (as adding a constraint on type to queries).
