/**
* The authorization package provides an authorization service that can be used to
* check whether users have the rights to perform certain operations.
*
*
*
*
* {@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.
