- Data type Token changed from uint64_t to std::string - Added new class "Request" that describes a JSON TCP request - Classes may now throw Responses for proper error handling - Removed JSON parsing from Logic - proper Error handling everywhere - Many small fixes - removed unnecessary includes - removed using namespace std everywhere
