clReflect equivalent of protobuf example

gistfile1.cpp

// You write a structure with reflect attribute, like this:
clcpp_attr(reflect)
struct Person
{
   int id;
   std::string name;
   std::string email;
};

// You modify it like this:
Person person;
person.id = 123;
person.name = "Bob";
person.email = "bob@example.com";

// You save like this:
clutl::WriteBuffer wb;
clutl::SaveJSON(wb, &person, clcpp::GetType<Person>(), 0, 0);

// Send to file, network, whatever...

// You load like this:
clutl::ReadBuffer rb(wb);
clutl::LoadJSON(rb, &person, clcpp::GetType<Person>());
