The Iterators

For the iterators we have to hack around a bit. The problem is as follows:

  template<int A>
  class outer
  {
    template<int B>
    class inner;
  };

C++ does not allow specialisation of the inner class when the outer class is not specialized.

So I had to create a baseclass for the iterators which is not inside another class. This base class can then be specialized, and the real Iterator class inherits from it. I gave it the somewhat clumsy name RefinementSubEntityIteratorSpecial.
