bug: `youtube-video` directive won't compile

I've installed via `npm install` (and I tried `bower` first even though I saw your last commit was to try and discourage people from using bower) and I can't get the directive to compile. I can see your script on my page and it's included as a dependency in my app. The `` is just sitting in the DOM uncompiled.

No errors are being thrown in the console.

Here's how I'm including it in my project:

``` javascript
import '../node_modules/angular-youtube-embed/dist/angular-youtube-embed.min.js';

angular.module('myApp', [

// App Plugins
'ionic',
'youtube-embed'
])
```

I'd prefer to bower install it and include it as a external script on my page as the I've done with the rest of my front end packages but I'm fine as long as it works.

Thanks for any help!

Reproduce the issue with the shown youtube-video markup, the import of dist/angular-youtube-embed.min.js, and the youtube-embed Angular module dependency. Inspect the directive registration and package entry points first; done means the element compiles into a YouTube embed without console errors.
