Show HN: A better Alexa SDK, with typescript

Background: I built this after using the official SDK and finding it less than ideal. The pipelining concept is inspired by the likes of node's express and C#'s OWIN as a neat, extensible way of adding things like logging and authentication etc.

It's also designed to take advantage of TypeScript's static type checker and autocompletion, while still being very concise to use from vanilla JavaScript.
