A weak pointer to an IMP::Object or IMP::RefCountedObject.
WeakPointers do not do reference counting and do not claim ownership of the pointed object. As a result, they can be used to break cycles in reference counted pointers. For example, since an IMP::Model contains a reference counted pointer to an IMP::Particle, the IMP::Particle has a WeakPointer back to the Model.
