return missing from queue_wrapped.py wrapped methods

[blgo]

Hello Zed,

I think this is a very good example of how to use composition in Python to wrap a class. However, the return functions are missing from "count" and "unshift".

def unshift(self):
"""Removes the head item and returns it."""
return self.list.unshift()

def count(self):
return self.list.count()
