Only leafs operates on values and only internal nodes operates on nodes.
There is no problem with it. The problem is with references to other
nodes. std::vectors can allocate memory somewhere else so the rtree
should probably be redesigned.

Moving to visitors shouldn't take long. The only one improvement is a
lot smaller vtables for nodes. We have a lot of virtual functions
pointers we could get rid of but I don't know if it will give us a big
performance change.
