    Good questions... Adherence to Google C++ Style Guide on references vs. 
pointers. I think I did this before writing my questions about the practice on 
the dev@geode. I can back this change out.
    
    For reference, the guide dictates that references must be const and should 
be used for in variables only. For out variable you should use pointer.
