public HuTuckerTransformationStrategy(Iterable<? extends CharSequence> iterable,
                                      boolean prefixFree)
```
    Creates a Hu-Tucker transformation strategy for the character sequences returned by the given iterable. The strategy will map a string to its Hu-Tucker encoding.
    
    Parameters:
    
    iterable - an iterable object returning character sequences.
    
    prefixFree - if true, the resulting set of binary words will be prefix free.
