-Custom Browser ES Module Loader
-===============================
-
-This is a module loader using babel and the ES Module Loader polyfill.
-It's based heavily on
-https://github.com/ModuleLoader/browser-es-module-loader, but uses
-WebWorkers to compile the modules in the background.
-
-To generate, run `npx rollup -c` in this directory, and then run
-`./genworker.js`.
