Composition/Delegation terminology

[JonathanAldrich]

I prefer to reserve the term Delegation to mean specifically the language construct, or design that closely reflects that construct--in particular, the delegator passes a pointer to itself to the delegatee, so the latter can call back into the former. I changed the Design for Reuse: Inheritance and Composition slides accordingly, along with the introductory text in lab 5.

However, the code for lab 5 still uses the Delegation terminology. It would be ideal to change this to reflect the lecture.
