Detailed Description

   template<typename _Tp>
       class std::__new_allocator< _Tp >"An allocator that uses global new, as per C++03
       [20.4.1].

       This is precisely the allocator defined in the C++ Standard.

       • all allocation calls operator new

       • all deallocation calls operator delete

       This is the default base-class implementation of std::allocator, and is also the base-
       class of the __gnu_cxx::new_allocator extension. You should use either std::allocator or
       __gnu_cxx::new_allocator instead of using this directly.

       Template Parameters
           _Tp Type of allocated object.
