Attributes:
self.called - records call even if no args, kwds passed.
self.result - set by init, returned by call.
self.args - captures positional arguments.
self.kwds - captures keyword arguments.
Most common use will probably be to mock methods.
Mock_tk.Var and Mbox_func are special variants of this.
