  		//	description:
  		//		A simple store that provides a datastore interface to a filesystem.  It takes a few parameters
  		//		for initialization:
  		//			url:	The URL of the service which provides the file store serverside implementation.
  		//			label:	The attribute of the file to use as the huma-readable text.  Default is 'name'.
  		//		The purpose of this store is to represent a file as a datastore item.  The
  		//		datastore item by default has the following attributes that can be examined on it.
  		//			directory:	Boolean indicating if the file item represents a directory.
  		//			name:	The filename with no path informatiom.
  		//			path:	The file complete file path including name, relative to the location the
  		//					file service scans from
  		//			size:	The size of the file, in bytes.
  		//			parentDir:	The parent directory path.
  		//			children:	Any child files contained by a directory file item.
  		//
  		//		Note that the store's server call pattern is RESTlike.
  		//
  		//		The store also supports the passing of configurable options to the back end service, such as
  		//		expanding all child files (no lazy load), displaying hidden files, displaying only directories, and so on.
  		//		These are defined through a comma-separated list in declarative, or through setting the options array in programmatic.
  		//		example:	options="expand,dirsOnly,showHiddenFiles"
