docs: Decorator routes an Alexa IntentRequest and provides the slot parameters to the wrapped function.
  
          Functions decorated as an intent are registered as the view function for the Intent's URL,
          and provide the backend responses to give your Skill its functionality.

          def weather(city):
              return statement('I predict great weather for {}'.format(city))
  
          Arguments:
              intent_name {str} -- Name of the intent request to be mapped to the decorated function
  
          Keyword Arguments:
              mapping {dict} -- Maps parameters to intent slots of a different name
                  default: {}
  
              convert {dict} -- Converts slot values to data types before assignment to parameters
                  default: {}
  
              default {dict} --  Provides default values for Intent slots if Alexa reuqest
                  returns no corresponding slot, or a slot with an empty value
                  default: {}
