Added Dockerfile

[ChrisTimperley]

Installs genprog to /opt/genprog and updates PATH. Can be used in combination with BugZoo to conduct reproducible program repair studies.

Can be manually constructed via:

docker build -t genprog .

To check that everything was built correctly, you can spin up an interactive shell to poke genprog:

$ docker run --rm -it genprog
> genprog
