ECMAScript 7 compatibility shims for legacy JavaScript engines.

`es7-shim.js` exports an object that contains shims that can be used to monkeypatch a JavaScript context to contain all ECMAScript 7 methods that can be faithfully emulated with a legacy JavaScript engine.
`es7-shim.browser.js` calls the “shim” method on the export of `es7-shim.js` which actually modifies the global object, including replacing native methods when engine-specific bugs exist.
Published on npm are `dist/es7-shim.js` and `dist/es7-shim.min.js` which are pre-prepared browserified versions of `es7-shim.browser.js`.

## Source for shims
Every shim in this module is a separate, independent `npm` module.
To be included, all shims must have a ".shim()" method that installs the shim into the global object whenever it is necessary. It should also handle any engine-specific specific to the method it is shimming.

## Tests
Simply clone the repo, `npm install`, and run `npm test`
