Last addition I swear. Now you can just run, for example: `docker run --rm -v $PWD:/work -it aflplusplus:latest ./build_script_in_working_dir.sh'. Had forgotten this but figured this would make things easier for folks.
The docker build has never worked for me. I fixed all the build errors, mostly due to missing dependencies. I also fixed silent errors that would allow for the build to finish but wouldn't contain features such as python mutators or QEMU's unsigaction module.
