+    macaroon associated with Ops (see MacaroonStore.MacaroonIdInfo for
+    how the associated operations are retrieved) and adding Caveats. If
+    the user succeeds in discharging the caveats, the authorization will
+    be granted.

+        :param ops: holds all the operations that were not authorized.
+        If ops contains a single LOGIN_OP member, the macaroon
+        should be treated as an login token. Login tokens (also
+        known as authentication macaroons) usually have a longer
+        life span than other macaroons.

+        authorize the above operations.
