[mkgmap-dev] Commit r4309: Improve code readability for KdTree, no functional change

Version mkgmap-r4309 was committed by gerd on Mon, 21 Oct 2019 Improve code readability for KdTree, no functional change I thought I should replace the recursive calls but that turned out to be quite complex and some investigation showed that the tree is typically well balanced when used in mkgmap so that the depth is well below 100 and threrefore not a problem with the java stack. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4309
