Objective C or C++ developer to improve class design

Hi Guys, Its a pretty simple task, this is what need to be done: - Look at the a few classes that I am going to send you (PM me after bidding to get it) - Improve the overal structure to make it better and more sophisticated. - Create a large (4-6) pages doc to talk about this design - You dont need to compile to code just add methods, classes and comment it! Just need good software design and documentation skill. Need to be done in 1-2 days.
