+	 * Mesh block's "file" Entry has changed. It is also used to correctly 
+	 * display the "file" Entry as commented/uncommented depending on the Mesh 
+	 * block's currently set type. Lastly, it will listen to updates from the
+	 * Mesh's active data node in case a new "file" Entry is ever manually
+	 * added (in which case it will register the new Entry with the form).
