Since they won't be used by the main application (ie - app.js, routing, etc, etc), just by features, they bubble up to the root 'features' directory that is contained in the scripts directory.

I forgot to add, I will also create a directory tree for singular service dependencies, so that a service can have multiple, non-shared, dependencies that are each considered a 'feature' and consequently have their own folder containing their code and tests.

I need to blog this, but node is fighting with osX on my macbook right now. I am not a happy camper.
