Subject: Splitting up C++ extractor (#1800)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Refactor out ClassLikeNode

* WIP around ScopeNode.

* Use push and popScope.

* Small improvements around C++ extractor.

* Adding dynamic casting support.

* Made Field another Node type.

* Disable command line dumping by default.

* Removed comment.

* Fix shadowed variable bug found on linux.

* Split out node.

* Renamed C++ extractor diagnostics to just diagnostics.cpp/.h

* Remove C++ extractor Options into separate options.cpp/options.h files.

* Split out parser and identifier lookup from C++ extractor.

* Put in CppExtract namespace.
Simplify some of the class names.

* Some simple renaming.

* Split out NodeTree from Parser.
