This is ok, hook_cpp_namespace is not really a C++ "namespace", but
rather a way to make sure that the names of the functions and
everything else created by the binding generator are unique.

Try just hook_cpp_namespace = "a_b"

To use a real C++ namespace use one of the
hook_cpp_binding_[XXX_includes] to add any code you need to the
bindings.

Let us know if the above works for you. I do not believe that I've
ever tried using classes within classes so there may be other issues
as well, but lets hope not.
