Easy serialization of classes

[jonasseglare]

I am currently using msgpack to serialize my objects in C++, but the msgpack is not human readable, so I am looking at using JSON. The msgpack-c++ library has a very neat macro called MSGPACK_DEFINE which, in one line, adds msgpack serialization to a class, so that it can be serialized/deserialized to the msgpack format. See example here: https://github.com/msgpack/msgpack-c/wiki/v1_1_cpp_adaptor#intrusive-approach

#include <msgpack.hpp>

struct your_class {
    int a;
    std::string b;
    MSGPACK_DEFINE(a, b);
};

Does this JSON library feature a similar functionality? It would be very useful.

I have not thought about going into the serialization business - I think it is a lot of work to do right, and that with cereal there is already a great library for this.

FYI: A nice serialization/deserialization for arbitrary types is now implemented: see #328.
