Sub directory support

[jloh]

Since the fix done in seejohnrun/haste-server#46 doesn't actually work anymore, is there any chance of getting directory support in this fork?

Hi,
I'm sorry, but at the moment I don't have the time to do any more work on this project.
Generally I didn't think 1 1/2 years ago, that there would be any interest in this NodeJs-learning-project of mine.

But feel free to implement this feature and submit a pull request.
