Detailed description:
Use CL_WeakPtr when you want to have a pointer that is reference counted by CL_SharedPtr but want a pointer that dont increase the reference count.The purpose of CL_WeakPtr is to avoid circular loop issues. By using CL_WeakPtr you can construct new CL_SharedPtr'ed objects based on the weak pointer.
