 When reading a spreadsheet containing dates or times, Spout returns the values by default as DateTime objects.
 It is possible to change this behavior and have a formatted date returned instead (e.g. "2016-11-29 1:22 AM"). The format of the date corresponds to what is specified in the spreadsheet.
