    //1.Create interface
    // 2.Create rest adapter
    // 3.Implemention for interface RestService
    //4.Consume APis


    //1.Create interface

        RestAdapter adapter = builder.build();
        adapter.create(RestService.class);

    }

    //4.Consume APis - Sync
    public List<Repo> getRepos(String gitUserName) {
        return getRestService().listRepos(gitUserName);
    }

    //4.Consume APis - Async
