Dependencies installation does not work in a proper way

I used npm to install kue with the following command:

`npm install kue`

I noticed that alle the kue's dependency have been installed in `node_modules` directory, while they should be installed inside `node_modules/kue` directory, following npm install algorithm (https://docs.npmjs.com/cli/install#algorithm).

Am I doing something wrong or is it a known issue?
- Node version: `0.12.2`
- npm version: `3.8.6`

Reproduce `npm install kue` with the reported Node 0.12.2 and npm 3.8.6 versions, then inspect how kue’s dependencies are declared and installed. Done means confirming whether the top-level `node_modules` layout is expected or correcting it so dependencies are placed under `node_modules/kue` as described by npm’s algorithm.
