The problem I am seeing is that I want to inherit from a virtual const function
but I don't want MY derived function to be const. Just because my parent class
thought the member should be const doesn't mean I agree, or am I simply
restricted? 

Thanks, and again I am sorry if this is simply a lack of my understanding of
C++.
