\subsection{Detailed Description}
\subsubsection*{template$<$typename Sort\+Policy$>$\newline
class mlpack\+::neighbor\+::\+R\+A\+Query\+Stat$<$ Sort\+Policy $>$}

Extra data for each node in the tree. 

For neighbor searches, each node only needs to store a bound on neighbor distances.

Every query is required to make a minimum number of samples to guarantee the desired approximation error. The \textquotesingle{}num\+Samples\+Made\textquotesingle{} keeps track of the minimum number of samples made by all queries in the node in question.
