Tree.js is a JavaScript library to build and manipulate hookable trees

I might be thick, but what's a valid use case for this? Tree-based navigation? (e.g. admin section in web-application to browse a 'file system')

That Tree Provider service looks intense. So pretty much the functionality I assumed.

Awesome project btw! Super detailed readme.

Thanks for you support!
