Enhanced C++ extractor (#1340)

* Extractor builds without any reference to syntax (as it will be helping to produce this!).

* Change macros to include the super class.

* Added indexOf(const UnownedSubString& in) to UnownedSubString.
Refactored extractor
* Output a macro for each type with the extracted info - can be used during injection in class
* Simplify the header file - as can get super type and last from macro now
* Store the 'origin' of a definition

* Some small tidy ups to the extractor.

* Improve comments on the extractor options.

* Made CPPExtractor own SourceOrigins

* Small fixes around SourceOrigin.

* Small tidy up around macroOrign
