Not work with browserify --standalone

Hi!,

I can't make to work this module with the option --standalone of browserify.

I initially use:

```
browserify index.js --standalone customerInsight > build/client.js
```

In this case, I can access to customerInsight object in the browser.
But, when I use:

```
browserify index.js --standalone customerInsight | bundle-collapser > build/client.js
```

I can't access to the object (customerInsight).

What am I doing wrong?

Thanks!
