data: Extended CxxParser to detect elements

Detects most elements in the code, currently classes, structs, global variables, fields, functions, methods, namespaces
and enums. The structs ParseLocation and ParseVariable are helper objects to transmit information to the ParserClient.
Currently the parsed information only gets logged in the Storage.
