Reorganize module loading.

We now use webpack instead of SystemJS, effectively bundling modules
into one file (plus commons chunks) for every entry point.  This results
in a much smaller extension size (almost half).  Furthermore we use
yarn/npm even for extension run-time dependencies.  This relieves us
from manually vendoring and building dependencies.  It's also easier to
understand for new developers familiar with node.

-> Recursively flatten an array or arrays. This is the fastest implementation of array flatten.
+> Recursively flatten an array or arrays.
 
-Why another flatten utility? I wanted the fastest implementation I could find, with implementation choices that should work for 95% of use cases, but no cruft to cover the other 5%.
+## Install
 
-## Run benchmarks
+Install with [npm](https://www.npmjs.com/):
 
-```bash
-npm run benchmarks
+```sh
+$ npm install --save arr-flatten
 ```
 
-Benchmark results comparing this library to [array-flatten]:
+Install with [yarn](https://yarnpkg.com):
 
-```bash
-#1: large.js
-  arr-flatten.js x 487,030 ops/sec ±0.67% (92 runs sampled)
-  array-flatten.js x 347,020 ops/sec ±0.57% (98 runs sampled)
+```sh
+$ yarn add arr-flatten
