#243: Dual cover tree traverser is quite slow

Comment (by rcurtin):
Some more improvements:
* jl-constructed cover tree, jl dual-tree traversal: 83962 (as before)
* jl-constructed cover tree, mlpack dual-tree traversal: 77506 (used to
be 98201)
* mlpack-constructed cover tree, mlpack dual-tree traversal: 107544 (used
to be 111024)
So we are now outperforming jl's implementation with his tree, but not
with the mlpack-constructed tree. Fortunately I still have one more trick
up my sleeve. The latest (somewhat hackish) improvements are committed in
r13979.
