Fixed that bug, using a slightly faster algorithm for the sort index than the simple fix would have used, and modified the tests that didn't have the correct expected result :-(
* Improved handling of named ranges, although there are still some issues (names ranges using a union type with an overlap don't handle the overlap twice, which as the MS Excel approach to set overlaps as opposed to the mathematical approach which only applies overlap values once)
* Fix tests that misused space and comma as simple separators in cell ranges
