Detailed Description

template<class T>
class DeepCopyPointer< T >

A "smart" pointer that implements deep copy and ownership. In other words, when the pointer is copied it copies the object it points to using "new". It also deletes the object it points to when it is deleted. Very useful for use as private data member of a class: it handles the copy construction, assignment, and destruction.
