+/**
+ * This Filter is designed to help MIGRATE users from systems that don't match the FQI style.
+ *
+ * Style 1, where just the ID is translated, i.e. OLD => new@something.onap.org, that is acceptable
+ * longer term, because it does not store Creds locally.  The passwords are in appropriate systems, but
+ * it's still painful operationally, though it does ease migration.
+ *
+ * Style 3, however, which is Direct match of Authorization Header to replacement, is only there
+ * because some passwords are simply not acceptable for AAF, (too easy, for instance), and it is
+ * not feasible to break Organization Password rules for a Migration.  Therefore, this method
+ * should not considered something that is in any way a permanent
+ *
+
+ *
+ * It goes without saying that any file with the password conversion should be protected by "400", etc.
