  # Takes a module (or multiple in reverse order), extends it with <tt>Interface::Abstract</tt>, then includes it into the current object

  # Example
  #
  #   module Remote
  #     # turns the device on
  #     def on
  #     end
  #   end
  #
  #   class Device
  #     implements Remote

  #     def on
  #       @power = true
  #     end

  # Conforms with naming conventions for include and extend

  # Returns an array of interfaces implemented by the current object
