/*
 * 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.
