I'm not sure if the code will work for one moved node. You first call
reIndexPrimitives(modified) that might move node to different bucket
and then try to get ways, that still think the node is in the old
buckets. Anyway after some modifications it should work, at least as a
temporary solution.

So I will replace direct access to QuadBuckets with getNodes() method
returning read-only collection and add search method. Internally
Dataset will use both QuadBuckets for fast access by coordinates and
Storage for fast access using id and iterations. Because dataset
modifications will be possible only through Dataset methods, it
shouldn't be problem to keep the two lists synchronized.
