Synopsis:            A class for types that can be converted to a hash value
Description:         This package defines a class, 'Hashable', for types that
                     can be converted to a hash value.  This class
                     exists for the benefit of hashing-based data
                     structures.  The package provides instances for
                     basic types and a way to combine hash values.
