fixing the bug which stopped treeLinkFeatures from working

function [linkList, featureList]= treeLinkFeatures(data, depthThresh)
%% linkList = treeLinkFeatures(data)
% given a dataset, a hierarchical cluster of the data is produced, and then
% the data is traversed, such that, for each split in the data, a set of
% features are produced, which are the ranked features that can be used to
% separate the given dataset at that point.



if(nargin < 2)
    depthThresh = 999;

linkList = depthCheck(linkList);

while (~isempty(currentRow))
    if(currentRow(1) > listSize)
