Subject: C++ Extractor (#1337)

* WIP: Doing texing using slangs lexer for cpp-extractor

* Node tree for C++ extraction.

* Bug fixing.
Add dump of hierarchy.

* First pass at extracting fields.

* Parse template types.

* Use diagnostics defs for C++ extractor.

* Simplify Diagnostic Defs.

* Remove the brace stack.

* Added IdentifierLookup.

* Add handling for >> style template close.

* Improved identifier handling/keywords.

* Added ability to check if reader is at cursor position.

* Handling of an unspecified root type.

* Parsing code comments.
Tidy up some parsing - to use advanceIf functions more.

* Improve path handling.

* Fixes around changes to Path interface.

* Working Range, Type and Scope header.

* Extract the middle part of marker and put in output. Gives more flexibility at macro injection, and in class definitions.

* Split DERIVED types into it's own macro, to provide way to generate for derived types.

* Fix clang/g++ compile issue.

* Tabs -> spaces.

* Fix small bug in getFileNameWithoutExt

* Small improvement around naming.
