Comment (by rcurtin):

 There were some errors I introduced with my modification (#264), so now
 with those fixed we are at:

  * jl-constructed cover tree, jl dual-tree traversal: 83962
  * jl-constructed cover tree, mlpack dual-tree traversal: 111225
 (originally 247537)
  * mlpack-constructed cover tree, mlpack dual-tree traversal: 132341
 (originally 189628)

 This is not doing parent-child prunes, so I need to reimplement that now
 (safely).
