Create project stub and folder structure
Move getConnection execution to mongoCtrl - now the whole mongodb connection establishing/renewal is located in mongoCtrl module.
Expose a unique endpoint for mongo queries (execute method) instead of exposing each method separately - done to centralize db connection establishment and management.
Refactor users api methods (style changes mostly).
Add newlines at the end of all files
Separated user data update from friends update. It should be more manageable now.
