list<pair<int,string> > gap_ls; 

 Which is under the private section. I would like to wrap this like one can do using a vector like this

 class_<std::vector<std::pair<double, double> > >("VectorOfPairs") 

                .def(vector_indexing_suite<std::vector<std::pair<double,double> > >());

and for pairs I had this

        class_<std::pair<double, double> >("DoublePair") 

                .def_readwrite("first", &std::pair<double, double>::first)

                .def_readwrite("second", &std::pair<double, double>::second);

But how do I write a wrapper for list<pair<int,string> >gap_ls; 

Any advice in this context would be appreciated.

Kind Regards
