/* CajaDirectory is a class that manages the model for a directory,
real or virtual, for Caja, mainly the file-manager component. The directory is
responsible for managing both real data and cached metadata. On top of
the file system independence provided by gio, the directory
object also provides:
1) A synchronization framework, which notifies via signals as the
set of known files changes.
2) An abstract interface for getting attributes and performing
operations on files.
