Right, you want to treat the original properties as read-only values; 
only subsequently modified values of your Properties need be written by 
invoking putXxx(). Conveniently, the getXxx() methods allow you to 
specify a default, which should be the value returned by getProperty().

The net effect is that only _changed_ properties are written to the 
(platform dependent) Preferences store. Similarly, the store may be 
deleted entirely to restore your (factory) defaults.
