  Build Isabelle docker image with default logic image, using a standard
  Isabelle application archive for Linux (local file or remote URL).

  Examples:

    isabelle build_docker -E -t test/isabelle:Isabelle2016-1 Isabelle2016-1_app.tar.gz

    isabelle build_docker -E -n -o Dockerfile http://isabelle.in.tum.de/dist/Isabelle2016-1_app.tar.gz
