Exclude/Include of relationships

At http://trailblazer.to/gems/representable/3.0/api.html#include-and-exclude there's a documenation about the top-level-options include and exclude. Today I tried to exclude a has_many relationship while using Roar::JSON::JSONAPI, but can't achieve it.

class ArticleDecorator < Roar::Decorator
  include Roar::JSON::JSONAPI
  type :articles
# a property exclude works
  property :id
  property :title
# a relationship exclude does not work
  has_one :author, class: Author, populator: ::Representable::FindOrInstantiate do 
    type :authors
    property :id
    property :email
  end
end
#===============================================
ArticleDecorator.new(article).to_json(exclude: [:title]) #works
ArticleDecorator.new(article).to_json(exclude: [:author]) # does not work

Is the feature limited to properties?

Yes, it's currently limited to scalar attributes..

Note that ArticleDecorator.new(article).to_json(include: [:author]) probably doesn't do what you expect either.

@wuarmin as with #2, this should now be fixed on master.
