Include code checkers
It would be nice to integrate some static code checkers into the CI. Some tools to look into could be:
- cppcheck http://cppcheck.sourceforge.net/
- krazy http://www.englishbreakfastnetwork.org/krazy
- vera++ http://www.inspirel.com/vera/
- cpplint https://google.github.io/styleguide/cppguide.html
In particular, this maybe could be used to enforce some code style as well.
