Code submission conventions

Hello everyone.

Chongsun and I have recently discussed and worked on the improvements toward code submission and code reviews. We've determined that we should standardize the commits that are getting merged to the master branch, therefore, a simple guide to the code submission strategy has been created. We believe that this will help us keep the repository clean and maintainable and at the same time make it easier during code reviews and when trying to find a specific change on the repository. We're asking everyone to take a look at the guide and adapt the commits that are pushed to the master branch so they conform to the conventions.

The document is available at: https://openlmis.atlassian.net/wiki/display/OP/Code+Submission+conventions

Feel free to ask if any of the points is not clear enough or if there's anything that you feel could be added to the code submission conventions.

Best regards,
Sebastian Brudziński.
