Dumber gist uses dumber bundler, the default bundle file
is /dist/entry-bundle.js.
The starting module is pointed to aurelia-bootstrapper
(data-main attribute on script) for Aurelia,
The aurelia bootstrapper then loads up user module "main"
(aurelia-app attribute on <body>) which is your src/main.ts.
