> It is often useful to know the number of unique elements in a frequency table. Could you add a simple method that returns the size of freqTable. It seems like it would be as simple as:
> {code}
> public int getUniqueCount(){
>      return freqTable.size();
> }
> {code}
> Given that freqTable is private, there is no way to extend the class and add this method. Thanks!
