Detailed Description
A base class for objects whose life-time can be tracked.
This class provides the ability to be observed by a observing_ptr, which is a smart pointer that is aware of the deletion of this object. It is used by the signal/slot system to automatically disconnect a slot when the receiving object has been deleted, and can wrap itself inside a function that guards against deletion of the object using bindSafe().
