[s0; Ptr and Pte&]
[s0; Ptr and Pte class templates provide a smart pointer system that 
cleared (assigned NULL) when pointed object is destructed. That 
makes it useful in situations where life`-time of object cannot 
be precisely determined.&]
[s0; While Ptr class template provides smart pointers, Pte is the 
class which adds necessary functionality to pointed objects. 
Ptr could only point to objects of Pte`-derived type. So to make 
a class `"Ptr`-able`" you should add Pte as one of class bases, 
with the derived class as its parameter, e.g.:&]
[s0; struct Foo : Pte<Foo> `{....&]
