data: Added CxxParser, currently only detecting classes

This change adds CxxParser a class for parsing cxx files. It holds basic functionality to detect classes using the clang
libTooling classes. CxxParser is derived from a common Parser interface, which can later be used for other language
parsers. The Parser forwards detected elements to a ParserClient interface, which is implemented by the Storage class.
The detected classes only get logged so far.
