/* Personal Feature: Carver
The MyFileItems class represents a directory and all of it's children (which are in turn MyFileItems)
The constructor recurses through the diretories ensure that each item is cached in ram and the size
of each folder in calculated only a single time.
I eventually figured out how to create this object without blocking the UI thread, but if I continue to
work on this in the future I would like to have the size calculated after the constructor so that folders
can be displayed to the user before size is avialable.
This class also handles the UnathorizeAccessException. When this excpetion occurs the class is marked as
Unathorized and can then be properly displayed throughout the application.
