public class HistorizedInputFactory
extends Properties

Generic class to provide historized user input - perhaps for a text-field. Can be used for comboboxes to configure their items.

 Use: 
 - call the create method 
 - use instance(name) with the created item name to get the created historized-input 
 - use getAsList() to obtain the entries - use addAndSave(value) to add a new entry.
