Compile warning "unused variable" in FloatTraits.hpp

Created by: m-andersen

I get the following compile warning under linux

I have included in my CPP file using #include "ArduinoJson.hpp"

and then reference it using namespace. ArduinoJson::DynamicJsonBuffer m_JsonBuffer; ArduinoJson::JsonObject &m_JsonRoot;
