Docker file in the python package --- to move

[smover]

The files:

• build_docker.sh
• [Dockerfile] https://github.com/cuplv/biggroum/blob/musedev_hackaton/python/fixrgraph/Dockerfile

are in the fixrgraph python package and refer to the musedev image (i.e., are in the wrong place).

We should move those files somewhere else, outside the python package (ideally, we could create a deployment folder at the toplevel of the repository and organize our docker files there)
