intrusive serialization

[bodomartin]

when trying to use intrusive serialization (e.g. with a member template 'serialize') I fail to compile the code. I have put a demo working with boost::archive::text_iarchive / test_oarchive in my fork (latest develop)

https://github.com/bodomartin/trial.protocol/

which is otherwise synced with your latest develop.
(using gcc 5.4.0, linux) - I noticed that when using a private serialize template the serializer_overloader does not find the member function? The boost serialization lib uses the 'access' friend.

I still have not found a good solution to this problem.

While I can easily change various templates to call the access members, the problem is that I need to detect if the class has the serialize or load/save members. Otherwise I get ambiguous template matching errors on other classes like std::string.
