Better model/migration code:
1. Add glob module as dep
2. Add 'define' property for model column definition
3. Export dbTypes as GLOBAL for usage in migration/model files.
4. Migration/model generators rewritten - define,associations,opts,up/down,..
5. If model not defined in app/model/ file, app will look at migration file (db/migrate/) for definition
