00030  * Id::IdStorage is a special base class, which is created
00031  * to simplify adding new storages which use ids instead of
00032  * paths in their API.
00033  *
00034  * Some Requests are already implemented, and Storage based
00035  * on IdStorage needs to override/implement a few basic things.
00036  *
00037  * For example, ListDirectoryRequest and ResolveIdRequests are
00038  * based on listDirectoryById() and getRootDirectoryId() methods.
00039  * Implementing these you'll get id resolving and directory
00040  * listing by path.
