* Hibernate3 interceptor used for getting the proper entity name for scoped
* beans. As scoped bean classes are proxies generated at runtime, they are
* unrecognized by the persisting framework. Using this interceptor, the
* original scoped bean class is retrieved end exposed to Hibernate for
* persisting.

* <p>Usage example:
*
* <pre>
* <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
* ...
* <property name="entityInterceptor">
* <bean class="org.springframework.orm.hibernate3.support.ScopedBeanInterceptor"/>
