AWS SAM, Swagger, API Gateway, Lambda Starter

Light-weight sample to show how to use the AWS Serverless Application Model (AWS SAM) to integrate API Gateway to a separate Swagger or OpenAPI file. The demo triggers a lambda function through API gateway, and then returns the parameters passed to it to show that you can acces these parameters inside the lambda function.
