     Constructor is protected (not public) for easy inheritance.  Josh Bloch's "Item 1" says public
     static factory methods are better than constructors because they have names, they can return
     an existing object instead of a new one, and they can return a sub-type.  Therefore, you
     have more flexibility with a static factory as part of your public API then with a public
     constructor.
