# Scope.new('Published', :public)

#
# Scope.new('Published', :public, :if => proc { current_admin_user.can?( :manage, active_admin_config.resource_class ) } ) { |articles| articles.where(:published => true) }
# # => Scope with name 'Published' and scope method :public, optionally displaying the scope per the :if block, using a block
#
# Scope.new('Published') { |articles| articles.where(:published => true) }
# # => Scope with name 'Published' using a block to scope
