public interface VariableType

Author:
Andrew H. Fagg and Steven Ness

An abstract implementation for specifying the variable that will be used as a key in our compareTo2 method. However, only the real class that implements this interface will define the enummerated type that actually contains the options for compareTo2.

Note: we introduce this interface here so that compareTo2 can accept references to objects of this type instead of type Object. What we get out of this is the compile-time check that the right things are being handed to compareTo2()
