C++ extern question
If I have a class in `outside.h` like:

    class Outside
    {
       public:
           Outside(int count);
           GetCount();
    }

How do I use it in `framework.cpp` using the extern keyword, where I need to instantiate the class and call `GetCount`?

EDIT: Include is not allowed.
