MemoryBasedPreferences
public MemoryBasedPreferences(MemoryBasedPreferences parent,
String name,
boolean isUser) Creates a new preferences node with the given name and parent.
When isUser is true it will be user node otherwise it will be a system
node. It will always set the newNode field to true
since there is no real backing store, so all nodes are new.
