Description Greg Woolsey 2017-08-16 23:49:12 UTC 
A Vaadin-Spreadsheet unit test uncovered a case overlooked in the initial implementation.  A cell can be completely undefined in the model (Row is null or Cell is null) but still have conditional formatting applied when the sheet is displayed in Excel.  This is because formula based rules don't have to refer to the cell(s) they apply to.
