Smart pointers are objects which store pointers to
dynamically allocated (heap) objects. They behave much like
built-in C++ pointers except that they automatically delete
the object pointed to at the appropriate time. Smart
pointers are particularly useful in the face of exceptions
as they ensure proper destruction of dynamically allocated
objects. They can also be used to keep track of dynamically
allocated objects shared by multiple owners.
