An AttributeSource contains a list of different {@link AttributeImpl}s, and methods to add and get them. There can only be a single instance of an attribute in the same AttributeSource instance. This is ensured by passing in the actual type of the Attribute (Class<Attribute>) to the {@link #AddAttribute(Class)}, which then checks if an instance of that type is already present. If yes, it returns the instance, otherwise it creates a new instance and returns it.
