+/** An operation class which implements high level import and export

+ *
+ * This class receivs a source and/or destination of keys as input and performs
+ * all steps for this import or export.
+ *
+ * For the import operation, the only valid source is an Iterator of
+ * ParcelableKeyRing, each of which must contain exactly a single keyring
+ * encoded as bytes.
+ *
+ * For the export operation, the input consists of a set of key ids and
+ * either the name of a file or an output uri to write to.
