# Examples:
#
# Scope.new(:published)
# # => Scope with name 'Published' and scope method :published
#
# Scope.new('Published', :public)
# # => Scope with name 'Published' and scope method :public
#
# Scope.new 'Published', :public, if: proc { current_admin_user.can? :manage, resource_class } do |articles|
# articles.where published: true
# end
# # => Scope with name 'Published' and scope method :public, optionally displaying the scope per the :if block
#
# Scope.new('Published') { |articles| articles.where(published: true) }
# # => Scope with name 'Published' using a block to scope
#
# Scope.new ->{Date.today.strftime '%A'}, :published_today
# # => Scope with dynamic title using the :published_today scope method
