Coding style

**This page gives rules and/or guidances to all developers that want to integrate some code to Jami **

C++ format rules are defined by this clang-format file: https://git.jami.net/savoirfairelinux/jami-daemon/blob/master/.clang-format

All developers are recommended to format their code using the script in jami-project/scripts/format.sh. This is done automatically (as a pre-commit hook) when using ./build.py --init
