Just made it to specify the event name with a regex or a callback instead of a string.

In fact there is no reason. I needed it quickly for another project and the common names was already taken on npm.

Thanks...makes sense now.

I used it in https://github.com/marmelab/phpcr-browser

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

Awesome project btw! Super detailed readme.

Thanks for you support!
