How to use

Just init call it before app start, like:

ObjectifyFactory objectifyFactory = //... you have to init Objectify before Garfa
Garfa garfa = new Garfa()
garfa.register([ ... list of models ... ])
garfa.objectifyFactory = objectifyFactory

If you're using Spring Framework it could be called on beans initialization (a @Configuration class), or on afterPropertiesSet() for InitializingBean
