Added cpp-dependencies config.

See https://github.com/tomtom-international/cpp-dependencies

Example output:

$ cpp-dependencies --stats .
21 components with 42 public dependencies, 59 private dependencies
Detected 7 nodes in cycles

Graph generation:

$ cpp-dependencies --graph dependencies.dot; dot -Tpng dependencies.dot
>dependencies.png
