Added convenient script to create docker containers needed

#!/bin/sh

cd $(dirname $0)

docker run -it -d -e "TERM=xterm-256color" -v `pwd`:`pwd` \

  -v $HOME/.bashrc:/root/.bashrc -w `pwd` \

  --name tutorial-x86-noweb -h tutorial-x86-noweb \

  registry.sw4j.net/sw4j-net/noweb/master:latest

docker run -it -d -e "TERM=xterm-256color" -v `pwd`:`pwd` \

  -v $HOME/.bashrc:/root/.bashrc -w `pwd` \

  --name tutorial-x86-nasm -h tutorial-x86-nasm \

  registry.sw4j.net/sw4j-net/nasm/master:latest

docker run -it -d -e "TERM=xterm-256color" -v `pwd`:`pwd` \

  -v $HOME/.bashrc:/root/.bashrc -w `pwd` \
