A utility for using CommonJS require in the browser and creating bundles.

## Require node_modules packages and node modules

In case of path which not starts with `.`, Require will look for file in node_modules (by checking in package.json).
If such package not found (for example `require('fs')`), result for this package will return empty object. 

```js
const somePackage = require('some-package');
const somePackage1 = require('./node_modules/some-package/index.js');
const fs = require('fs');

module.exports = {somePackage,somePackage1,fs}
```

In case above `somePackage` and `somePackage1` should return the package, but fs, should return empty object. 

Pay attention, in browser, using `'./node_modules/some-package/index.js'` instead `'some-package'`, you save extra request/readFile for looking the filename.
