 * Extend to setup Eureka RESTful web services. This abstract class sets up
 * Guice and Jersey and binds the authentication and authorization filters that
 * every Eureka web service should have. It also sets up JPA-based persistence.
 * Role information will come from JPA through a data access object that is
 * bound to {@link org.eurekaclinical.standardapis.dao.UserDao} in your Guice 
 * configuration.
