Remove koans directory from source control.

Browse Source 
Patches were submitted against the koans directory rather than the
src directory. This lead to potential problems when we regenerate the
koans directory from scratch, leading to the very real possibility
that changes could be lost.

Please make all changes to the src directory and use "rake gen" (or
"rake regen") to generate the koans directory as needed.

# 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 sent.
#
# The proxy class is started for you. You will need to add a method
# missing handler and any other supporting methods. The specification
# of the Proxy class is given in the AboutProxyObjectProject koan.

# NOTE: The Television class is defined below
tv = Proxy.new(Television.new)
# HINT: Proxy class is defined above, may need tweaking...
