* Gulp file modified and configured to run server tests using mocha
* Server should be able to render default index.html
* Server should be able to handle get and post requests
* Data is currently stored in a storage object on the app.js file
* testindex.html was included in the client for my own testing and for the curious. We can remove it on the next pull request when everyone's on the same page.
