public interface TranslatorFactory<P,D>

A translator knows how to convert between a POJO and a native datastore representation. When an entity class is registered, the known TranslatorFactories are queried to produce a translator for that class; this translator will in turn be composed of translators for all of the fields, etc. These translators become a static metamodel that can efficiently convert back and forth between the formats with minimal runtime overhead.

P is the pojo type, D is the datastore type.
