Convert a string to json object properly

Some of us ran into problem when it came to converting a std::string or a const char* string properly to json object by nlohmann (https://github.com/nlohmann/json).
Here is how I achieved it :

 #include <string> #include <iostream>> #include <sstream> #include "json.hpp" using namespace nlohmann; json toJson(const char* jsonString){ json jsonObj; std::stringstream(jsonString) >> jsonObj; return jsonObj; }
