Your solution is pretty close to what I had in the first place. The 
reason I didn't like it was because of all the "new"s. CA and CB don't 
contain any data, but must be new'ed nonetheless. Furthermore, in your 
code you have to keep passing the C class to each call on CA and CB: not 
a viable solution.
