-/** 
- * A crude mechanism for using a filesystem as object storage.
- *
- *  This object represents a directory; writing a string, number, or
- *  boolean to any of its properties will create a file with the
- *  (encoded) property name as its filename and the "stringified"
- *  value as its contents.
- *
- *  Writing 'null' to one of this object's properties will
- *  [recursively if necessary] delete the corresponding directory
- *  entry.
- *  
- *  Writing any other object to one of this object's properties will
- *  create a new Directory object and copy the other object's keys()
- *  into the new Directory.  This means that assigning one directory
- *  to a property of another directory will <i>copy</i> the directory,
- *  not move it.  There is currently no way to move directories.
- *
- *  If an object is written to a property that already has an entry,
- *  the old one is deleted (equivalent to writing 'null') first.
- * 
- *  WARNING: when instantiating a Directory object with a file
- *  argument that points to a non-directory File, this class will
- *  delete that file and create a directory!
