Detailed Description

   template<typename _Tp>
       class __gnu_cxx::_ExtPtr_allocator< _Tp >"An example allocator which uses a non-standard
       pointer type.

       This allocator specifies that containers use a 'relative pointer' as it's pointer type.
       (See ext/pointer.h) Memory allocation in this example is still performed using
       std::allocator.
