Versioning

The versioning of this project is based on Semantic versionning :

• The patch is incremented when we fix a bug on a released version (most of the time using a hotfix branch).
• The minor is incremented when we release a new version with new features. It corresponds to a merge of develop into master.
• The major should be incremented when a breaking change is made to the application. We still have to define what is a breaking change in the context of this project. For now, I suggest that it stays 0 until we have a fully functionning firmware suited for the final user.
