Bug 201368 Support "Not In" operator in filter list
Description: After we support "IN" filter we should also support the "Not In" filter. Data part has already support the "Not In" filter, so hope model can support that operator in the filter operator list. Regards!

LabelHandle labelHandle = (LabelHandle) designHandle

		LabelHandle labelHandle2 = (LabelHandle) designHandle
				.findElement( "label2" );
		assertNotNull( labelHandle.getStyle( ) );
		assertEquals( "italic", labelHandle2.getStyle( ).getFontStyle( ) );
		
		copyContentToFile( newFilePath, baseFilePath );
		
		CssStyleSheetHandle sheetHandle = (CssStyleSheetHandle) designHandle
				.getAllCssStyleSheets( ).get( 0 );
		designHandle.reloadCss( sheetHandle );
		
		SharedStyleHandle styleHandle = labelHandle.getStyle( );
		assertNull( styleHandle );
		
		SharedStyleHandle styleHandle2 = labelHandle2.getStyle( );
		assertNotNull( styleHandle2 );
		assertEquals( "oblique", styleHandle2.getFontStyle( ) );
