[mkgmap-dev] patch Interface Locatable and Kd-tree

Hi Steve, I plan to use a KD tree in the house number code. I noticed that the existing Kd-tree implementation in MapPointKdTtree is only usable with MapPoint instances, although it only uses the getLocation() method . I think this should be replaced using general interface Locatable() with method getLocation() and and general Kd-Tree implementaion for classes that implement the Locatable interface. The attached patch shows what I mean. What do you think about it? Do you see better names or packages for this? Gerd
