/**
 * A RoleServiceImpl is a Spring supported transactional implementation of a general {@link RoleService}. Using Spring 2 annotation support
 * autowires collaborators, therefore XML configuration becomes obsolete. This class is marked with Springs {@link Service} annotation to
 * benefit from Springs exception translation intercepter. Traditional CRUD operations are delegated to a {@link RoleRepository} instance.
