Description

The README.md for the cpp project has grown long and contains a lot of information specific to contributors. Move this information into a separate CONTRIBUTING.md

In particular, draw more attention to the cmake option `-DBUILD_WARNING_LEVEL=CHECKIN` which is used in Travis and includes `-Werror`
