There are 2 ways to solve the problem. I will not like both of them.

1. Add custom code to class A:

class_<std::vector< boost::shared_ptr<A> > >("AVec")
        .def(vector_indexing_suite<std::vector< std::vector<
boost::shared_ptr<A> > > >())
    ;

And then from Python create a reference from global scope to it:

AVec =3D A.AVec

http://boost.org/libs/python/doc/v2/indexing.html

2. I will accept the patch. Now when I think about it, it should be
fairly simple.
    1.  There is a need for vector_indexing_suite_ code creator.
    2.  After this small modification should be done to types_database_t.
         It should recognize, that data type is vector or map.
         pygccxml.declarations.templates parser will do the job easier
    3.  Modify module_creator.creator_t class

I am running out of time, otherwise I would implement the patch by myself.
I think it should take like 3-5 hours.
