def init_app(self, app, path='templates.yaml'):
        """Initializes Ask app by setting configuration variables, loading templates, and maps Ask route to a flask view.

        The Ask instance is given the following configuration variables by calling on Flask's configuration:

        `ASK_APPLICATION_ID`:

            Turn on application ID verification by setting this variable to an application ID or a
            list of allowed application IDs. By default, application ID verification is disabled and a
            warning is logged. This variable should be set in production to ensure
            requests are being sent by the applications you specify.
            Default: None

        `ASK_VERIFY_REQUESTS`:

            Enables or disables Alexa request verification, which ensures requests sent to your skill
            are from Amazon's Alexa service. This setting should not be disabled in production.
            It is useful for mocking JSON requests in automated tests.
            Default: True

        `ASK_VERIFY_TIMESTAMP_DEBUG`:

            Turn on request timestamp verification while debugging by setting this to True.
            Timestamp verification helps mitigate against replay attacks. It relies on the system clock
            being synchronized with an NTP server. This setting should not be enabled in production.
            Default: False

        `ASK_PRETTY_DEBUG_LOGS`:

            Add tabs and linebreaks to the Alexa request and response printed to the debug log.
            This improves readability when printing to the console, but breaks formatting when logging to CloudWatch.
            Default: False
