```
    Returns an iterator ranging from head to tail, inclusive.
    
    If tail is the element immediately preceding head in this HashChain, the returned iterator will iterate 0 times (a special case to allow the specification of an empty range of elements). Otherwise if tail is not one of the elements following head, the returned iterator will iterate past the end of the HashChain, provoking a NoSuchElementException.
    
    Specified by:
    
    iterator in interface Chain<E>
    
    Throws:
    
    java.util.NoSuchElementException - if head is not an element of the chain.
