class StringView:
    """
    StringView implementation using minimal copying with maximum use of
    reference semantics. Creating a sub-view of an existing StringView using
    either object slicing or constructing one from another will reüse the same
    source string object, using a reference rather than a copy.
    The contents() method can similarly be used to get an iterator (Generator)
    to access the view contents sequentially without putting it all in memory
    at once.
    A brand new string object is only created if the StringView is cast to str.
