'Array function to rank a range with unique ranks.
'vCountFrom determines from where you count in case of duplicates:
'1 = first rows (1 to count), then columns (1 to count), i. e. top left to top right (tltr)
'2 = starting with top right to top left, then downwards (trtl)
'...
'8 = starting with bottom right to top right, then to the left (brtr)
'If bJustNumeric is True then Rank will be used to rank, if False then Countif will be used.
'lOrder is like Rank's order: 0 = Descending, 1 = Ascending
