/**
* Demonstrates custom interpretation of entity-name through
* an Interceptor.
* <p/>
* Here, we are generating dynamic
* {@link java.lang.reflect.Proxy proxies} on the fly to represent
* our entities. Because of this, Hibernate would not be able to
* determine the appropriate entity mapping to use given one of
* these proxies (they are named like $Proxy1, or such). Thus, we
* plug a custom Interceptor into the session to perform this
* entity-name interpretation.
