# Answer to a ruby koan:
# Project: Create a Proxy Class
# In this assignment, create a proxy class (one is started for you
# below). You should be able to initialize the proxy object with any
# object. Any messages sent to the proxy object should be forwarded
# to the target object. As each message is sent, the proxy should
# record the name of the method send.
