Base class for interfaces.

Interfaces define and document an interface for a class. An interface class's name must begin with I, and all its methods should have no implementation code.

Objects that implement an interface should have an attribute __implements__, that should be either an Interface subclass or a tuple, or tuple of tuples, of such Interface classes.

A class whose instances implement an interface should list the interfaces its instances implement in a class-level __implements__.

For example:
   | class IAdder(Interface):
   |     'Objects implementing this interface can add objects.'
   |
   |     def add(self, a, b):
   |         'Add two objects together and return the result.'
   |
   | class Adder:
   |
   |     __implements__ = IAdder
   |
   |     def add(self, a, b):
   |         return a + b
You can call an Interface with a single argument; If the passed object can be adapted to the Interface in some way, the adapter will be returned.
