+/**
+ * The authorization package provides an authorization service that can be used to 
+ * check whether users have the rights to perform certain operations: 
+ * <br/>
+ * <img src="doc-files/Class_Diagram__org.wamblee.security.authorization__main.jpg"/>
+ * <br/>
+ * 
+ * {@link AuthorizationService} is the entry point. There is one POJO based implementation 
+ * {@link DefaultAuthorizationService}. In addition, there is {@link org.wamblee.security.authorization.jpa.JpaAuthorizationService}
+ * which caches an authorization service for efficiency (i.e. {@link DefaultAuthorizationService} is an entity);
+ * 
+ * The {@link DefaultAuthorizationService} uses a number of authorization rules to determine 
+ * whether access allowed. One generic {@link UrlAuthorizationRule} is provided which 
+ * determines whether a given user can perform a specific operation for a specific resource
+ * type at a specific URL is allowed. 
+ * 
+ * The authorization service needs to access the current user through the 
+ * {@link org.wamblee.security.authentication.UserAccessor} and needs access to the 
+ * {@link org.wamblee.security.authentication.UserAdministration} to check whether the 
+ * user belongs to certain groups.
