This example demonstrates a simple way to create your own virtual filesystems.
By extending the _File and Directory classes, you can easily create a tree
based on various datasources.

The most obvious example is the filesystem itself. A more complete and documented
example can be found in:

lib/Sabre/DAV/FS/Node.php
lib/Sabre/DAV/FS/Directory.php
lib/Sabre/DAV/FS/File.php
