added package.json to track dependencies

- [ ] Recommend updating `scripts.test` and `scripts.start` in `./package.json` to correct commands (include environment definition example, etc)
- [ ] Recommend updating dependency versions to run on current version of Node (when trying to run on Node v0.10.26 I received the following error related to commands used in the older versions of some packages)

> Error: require.paths is removed. Use node_modules folders, or the NODE_PATH environment variable instead.

Otherwise, a cool project!!
