Detailed Description

implements a WeakPointer class to deal with circular reference problems.

The WeakPointer class implements smart pointer semantics without increasing the reference count. It registers itself at the Object it points to in order to get notified of its destruction and sets its internal pointer to 0. To be able to access an object through a weak pointer, you either use SmartPointer(const WeakPointer&) or the WeakPointer::Lock() method. The first approach throws a BadWeakPointerException if the object has been destroyed, the second returns an empty SmartPointer.
