	 * Defines the common methods for the filter factory classes used in the FilterWorkbench application.
	 * Each IFilterFactory implementer has specific properties or methods for setting values for its specific
	 * filter. The interface's getFilter() method is used to retreive the filter in its current state.
	 * 
	 * Although it can't be explicitly enforced by the compiler, each IFilterFactory implementer should provide
	 * a flash.events.Event.CHANGE event indicating that the filter has changed. For this reason IFilterFactory 
	 * implementers must also implement flash.events.IEventDispatcher.
