Reminder to all repository users: Please do not add , commit and push any data files to your remote git repositories. The disk space the Git server is limited, it wasn't dimensioned to host anything else than code. Solely your code files need versioning. The data inputs/outputs don't. A good idea is to do "git add" individually on each file you want to commit, to avoid versioning unwanted content.
