Towards fix for Issue #1 : Refactoring code
Separation into directories
1. db - contains the db-layer code
2. config - currently contains the routes.js which has the routing information
3. service - contains api.js used by routes to invoke specific DB methods
Also removed currently unwanted packages from package.json
