docs: Calculates the distance between the argument instance and its nearest neighbour as well as the distance between that
  nearest neighbour and its own nearest neighbour. The ratio of these distances is compared to the threshold value, tau,
  and converted into a vote score.
  
  @param inst the instance to get votes for.
  
  @return the votes for the instance's label [normal, outlier]
