Git integration

Git integration can be enabled by setting the environment variable EDFLOW_GIT, e.g.

export EDFLOW_GIT=1

This assumes that you are starting edflow in a directory which is part of a git repository. For every run of edflow, git integration amounts to creating a tagged commit that contains a snapshot of all tracked files at the time of the run. You can get an overview of all tags with git tag. This allows you to easily compare your working directory to the code used in a previous experiment with git diff <timestamp>_<name> or two experiments you ran with git diff <timestamp1>_<name1> <timestamp2>_<name2>. Furthermore, it allows you to reproduce or continue training of an old experiment with git checkout <timestamp>_<name>.

Note however that only tracked files are included in the commit (we run git add -u in the background) and no new files are added. It is your responsibility to make sure required files are tracked.
