Packages you will use:

You will use the express package as your server.
You will use the node­uuid package in order to generate unique id’s to use as your identifiers.
You can read up on node­uuid (https://github.com/broofa/node­uuid) on the Github project page.
You will also use the mongodb (http://mongodb.github.io/node­mongodb­native/2.1/) package.
Your Routes
Any issues should result in a properly failed status code and a description of the error in JSON.
Requirements

1. You must not submit your node_modules folder
2. You must remember to save your dependencies to your package.json folder
3. You must do basic error checking in each function 1. Check for arguments existing and of proper type.
2. Throw if anything is out of bounds (ie, trying to perform an incalculable math operation or accessing data that does not exist)
3. If a function should return a promise, instead of throwing you should return a rejected promise.
4. You must remember to update your package.json file to set app.js as your starting script!
