[mkgmap-dev] splitter r325: improved split algo and new option

Hi all, I've applied num-tiles-v1.patch and improved the split algo, see http://gis.19327.n5.nabble.com/mkgmap-ToDo-list-tp5803388p5805165.html It is now less likely that splitter creates tiles with a low number of nodes, it is more likely that all tiles have nearly the same number of nodes, and typically you will see fewer tiles. Maybe this also means that you can increase the max-nodes value. I hope this also reduces the need for complex interactions between spltter and mkgmap. Gerd
