v.0.2.12

This version allows passing const- and rvalue references to functions mandatory, optional, optional_no_default, optional_null.

The template class json_dto::binder_t was refactored and now it uses several customization points (binder_data_holder_t, binder_read_from_implementation_t, binder_write_to_implementation_t). Those customization points can be used for solving tasks like described in #11. See more in the corresponding README section.

There are several new examples that show the new functionality: one, two, three.
