Refactored routes into models

app now uses config settings (defaults to development).
This means that:
- linkshare_test is used by default development
- linkshare is used for production
- Mongodb eliminated in place of mongoose schema

working routes:
- /users GET, POST
- /tiles GET, POST

unworking routes
- /tiles DEL
- /

Added wrecker test cases + wrecker.yml
moved routes to a routes file, renamed dir routes->controller
