// This file is an interface for the HashableObject class. This class is an
// abstract base class definig the necessary functionality of a hashable obj.
// The class includes a string key and leaves the derived classes to assign
// a value associated with a string key. The hashable object should be able to
// generate its own hash and return both the key and value.
