+    A simple "settings" implementation.  Load/Edit/Save settings for your programs
+    Uses json file format which makes it trivial to integrate into a Python program.  If you can
+    put your data into a dictionary, you can save it as a settings file.
+    
+    Note that it attempts to use a lookup dictionary to convert from the settings file to keys used in 
+    your settings window.  Some element's "update" methods may not work correctly for some elements.
