    This node server serves the static files and provides a CRUD interface
    used by backbone to store and retreive data.
    
    The store used here is non persistent so all the data will be lost when
    the server shuts down. However, if you wanted to store data into a database,
    you would just have to modify the store and this part of the code would remain intact.
