module ZohoHub
  # Allows adding attributes to a class, as <tt>attr_accessors</tt> that can then be listed from the
  # class or an instance of that class.
  #
  # === Example
  #
  #   class User
  #     include ZohoHub::WithAttributes
  #
  #     attributes :first_name, :last_name, :email
  #   end
  #
  #   User.attributes # => [:first_name, :last_name, :email]
  #   User.new.attributes # => [:first_name, :last_name, :email]
  #
  #   user = User.new
  #   user.first_name = 'Ricardo'
  #   user.last_name = 'Otero'
  #   user.first_name # => "Ricardo"
