-"""Executable Python script for a proxy service to dockerSkeleton.
-
-Provides a proxy service (using Flask, a Python web microframework)
-that implements the required /init and /run routes to interact with
-the OpenWhisk invoker service.
-
-The implementation of these routes is encapsulated in a class named
-ActionRunner which provides a basic framework for receiving code
-from an invoker, preparing it for execution, and then running the
-code when required.
