I'm not familiar with how to use clone allocators in ptr_container yet, so
I'll have to read through the documentation first to make sure I know how to
use them. Given that, at what point will I need to be calling
get_clone_allocator()? I figured I would just give ptr_vector my clone
allocator and never need it back from the container. I expect my clone
allocator to call the appropriate allocation method in its implementation
details, which as I showed in an earlier example, will be a function located
in the DLL itself.
