Make asynchronous

[jednano]

By using the async version of glob and providing a calling a callback method.

I'm already working on this. Check out the async branch. It's not done yet, as I'm investigating streams support as well.

Great! I'll be following the project.

BTW, I just published simple-glob, which is really all your code, ported over from Grunt. I've given the proper attributions. I've just always loved the way Grunt negated files and such. It's so easy. Not sure if that could be made async as well though.

This library (globule) is everything from Grunt, separated into its own module, made async, with a handful of improvements.

I see. Well, I was having problems with negation, so maybe I was doing something wrong. I'll revisit it. Thanks.
