+    Demo - User Settings - Config.ini format
+    
+    There are now 2 types of settings files available through the UserSettings APIs
+        1. JSON - .json files
+        2. INI - Config.ini files
+
+    The default is JSON files.
+    
+    If you wish to use .ini files, then you can do so using the UserSettings object.  The function interface
+    for the UserSettings API does not support .ini files, only the object interface at this time.  You'll see
+    why by looking at this demo.
+    
+    JSON settings:
+        settings['key']
+        
+    CONFIG.INI settings:
+        settings['section']['key']
+    
+    NOTE - There is a setting (default is ON) that converts True", "False, "None" into Python values of True, False, None
