[#58] Added Dockerfile

[jnguyenx]

Species can be selected through a build argument:

docker build --build-arg species=all -t owlsim-all . # default if no args is provided or not matching any species
docker build --build-arg species=human -t owlsim-human

[cmungall]

Remind me about the jobs that populate

https://data.monarchinitiative.org/owl/

Ideally there would be as few dependencies as possible on moving parts. It seems this all-hp.owl may be something created just for owlsim?

I created that by hand for now, just for @tudorgroza and also see if it worked. See #58
