Koa middleware to serve a Single Page App

The main purpose of this middleware is to support url rewriting for Single Page Apps that have a router. It creates a new endpoint in your koa app. This new endpoint serves files from a configurable directory, default value is /app. If you have an SPA that has a router, for example a React app that uses react-router, and your app has a path lets say /terms, if you refresh the browser's window, your app will display the homepage but you really would like it to display the Terms page. This middleware solves that for you, it will rewrite all paths to /index.html by default. It hands over the control of the pages to your SPA's router after a hard browser's refresh.
