Hello there, this package contains the Graph datastructure I found in the other day on someone else's github repo (sorry I really forgot which one) and graph algorithms I coded based on it. Feel free to use this packge and perhaps add new functionalities to it.
My compiling environment is based on C++ 14, so if your local gcc setting is something older C++ standards that throws tons of warnings, try adding -std=c++14 to your compile command.
