 *
 * This function is the Kokkos analog to std::atexit.  If you call
 * this with a function f, then your function will get called when
 * Kokkos::finalize is called.  Specifically, it will be called BEFORE
 * Kokkos does any finalization.  This means that all execution
 * spaces, memory spaces, etc. that were initialized will still be
 * initialized when your function is called.
 *
 * Just like std::atexit, if you call push_finalize_hook in sequence
 * with multiple functions (f, g, h), Kokkos::finalize will call them
 * in reverse order (h, g, f), as if popping a stack.  Furthermore,
 * just like std::atexit, if any of your functions throws but does not
 * catch an exception, Kokkos::finalize will call std::terminate.
