Create docker container for BIOVARS

[colombelli]

Descriptions

Given the many installation issues reported by different users, we decided to provide a docker container for the package. The docker container should be directly downloadable from docker hub, so the user only needs to run it and start using everything BIOVARS has to offer.

This, in addition to the changes of https://github.com/bioinfo-hcpa/biovars/issues/2 should provide a great usability for the users. The ones not interested in visualizations can simply install the Python package; and the ones interested in everything but with little technical background, can reduce the setup burden by executing the code through the docker container.

DoD

• [x] Dockerfile is added to repository
• [ ] ~bioinfo-hcpa has an account in Docker Hub~
• [x] Builded image is uploaded and downloadable through Docker Hub
• [ ] Container is properly tested with paper's study case walkthrough (everything should be working properly)

I'll skip the DoD related to bioinfo-hcpa account creation due to the recent difficulties regarding accesses. In the future, we may revisit this decision if needed.
