endpoints | Simple endpoint and action routing

Your handler or entrypoint file and function should look something similar to what is outlined below. First, any customizations of the EndpointRouter. Then, you create an instance of the classes containing your @endpoint mappings, and their dependencies, as appropriate. Lastly, you expose EndpointRouter.handle as the entrypoint so it can take ownership over properly routing your requests. We recommend you use a .rest postfix on your export in case you want to handle different event trigger types for this lambda function. For example, if you wanted to also listen to an SNS topic you would create another exported fucntion module.export.sns and wouldnt have to worry about remapping module.export.rest.
