/**
 * Java 5 annotation for describing service layer security attributes.
 * 
 * The Secured annotation is used to define a list of security 
 * configuration attributes for business methods.  This annotation can be used 
 * as a Java 5 alternative to XML configuration.
 * 
For example:
 * 
 *     @Secured ({"ROLE_USER"})
 *     public void create(Contact contact);
 *     
 *     @Secured ({"ROLE_USER", "ROLE_ADMIN"})
 *     public void update(Contact contact);
 *     
 *     @Secured ({"ROLE_ADMIN"})
 *     public void delete(Contact contact);
