Class Reference::Able

class Able : public Reference::HeapTracked 

Combined with the Reference::To template class, this class may be used to eliminate both memory leaks and dangling references. Simply inherit this class as follows:

class myKlass : public Reference::Able { … };

myKlass can now be managed using a Reference::To<myKlass>.
