+ * Id::IdStorage is a special base class, which is created
+ * to simplify adding new storages which use ids instead of
+ * paths in their API.
+ *
+ * Some Requests are already implemented, and Storage based
+ * on IdStorage needs to override/implement a few basic things.
+ *
+ * For example, ListDirectoryRequest and ResolveIdRequests are
+ * based on listDirectoryById() and getRootDirectoryId() methods.
+ * Implementing these you'll get id resolving and directory
+ * listing by path.
