/**
 * DummyPLSecurityManager is a dangerous class I had to make to allow
 * certain operations that are inconsistent with the security model:
 *
 * <ul>
 * <li>You can rename an object if you can modify it, but rename entails
 *     both creation and deletion.
 * <li>You need to be able to delete and create dimension and measure
 *     objects, and related data when you are renaming or editting a kpi
 *     for which you don't have delete permission.
 * <li>Other such inconsistencies.
 * </ul>
 *
 * <p>An instance of this class blindly permits all operations.  If
 * you need to use this class under circumstances different from those
 * listed above, discuss it with someone first.  There is probably a
 * better way.
