[Cppcms-users] Feature Request: Feature added to cppcms::rpc::json_method

[Daniel V. <chi...@gm...>]

Hello Ayrtom.

I added (see attachment) a feature to cppcms::rpc::json_method and it's
binders.

The feature allow to bind parameters of type:

        const cppcms::json::value const & 
        cppcms::json::object const &
        cppcms::json::array const &
        std::string const &

The forwarding of these types are passed by reference (zero copy
overhead).

For Example we can add a json rpc method of type:

void my_rpc::my_method(json::array const& a, json::object& o,
json::value& v);
...
bind("my_method",
   json_method(&my_rpc::my_method,this),
   json_rpc_server::method_role);  
...


In theory the changes no breaks backward compatibility and ABI. 

In practice my whole project compile with it without change.

Please review the code if you wish.

Thank you.
