max_dist in search function

[traum100]

Thanks for releasing great works.

"ikd_Tree.cpp", 886 line.
if (dist <= max_dist && (q.size() < k_nearest || dist < q.top().dist))
is it right?

or
if (dist <= max_dist*max_dist && (q.size() < k_nearest || dist < q.top().dist))

It should be max_dist * max_dist in that line. I have fixed the bugs on all the branches.

Many thanks for your careful reading and your notice!
